Hey guys just wandering how you would tell the difference between a motorway and a dual carriageway as im on a cbt and not full liscence i cant ride on the motorway and as im on a 50cc i wouldnt really want to but i cant tell the difference i tried google but that didnt really help either :) thanks
 
M/way - Blue Sign
D/way - Green Sign

But be aware some Dual Carridgeways can sometimes lead straight onto M/ways. Theres on in Bolton for instance A666 joins the M61 without much warning.

A motorway will be signposted with an 'M' in its label, for example 'M25' these will have 3 lanes and a crash barrier down the centre!

Dual carriageways will be 'A' roads with 2 lanes on each side :) ...They may also have a division or crashbarrier in the centre at times but this doesnt mean they are motorways so dont worry! Just make sure you stick on the left hand side so you dont get some arse hole ramming you from behind as people do floor it on dual carriagways and if they have a divider between opposing direction then you can go to 70mph!
 
the a1 has a motorway in it (a1(m)). there is entrances and exits just before the motorway starts and finishes, so you can ride on the (a1) without going on the motorway by mistake if you are restricted with CBT.
 
Some of us should make you a short vlog, highlighting and demonstrating some clear differences between major A roads and motorways. :)

I don't even know where the nearest motorway to me is. There's none in my neck of the woods.
 
A dual carriage way is I identical to a single carriage way except the division between opposing road traffic be it grass, walkways and barriers etc. Sometimes consisting of 1 or more lanes either side.

Motorways will be sign posted prior to entering them and have solely blue signs, typically a hard shoulder and lane barriers/concrete dividers. If a road turns into a motorway there is normally a sign diverting non motorway traffic away from the route. So don't panic you'll be fine.
 
Tip... Unless you can't avoid it, don't take your 50cc on a dual carriageway.

Yes legally you can do it but that won't help if you're flattened by a lorry that just didn't appreciate that someone would be doing 29.5mph or less on a 70 mph road.

Oh and not all A roads are dual carriageways and not all dual carriageways have 2 lanes either side.

Dual Carriageway refers to a road that features a divider that a vehicle should not or cannot cross. The dividers split the road into two carriageways with as many lanes as they wish, going in opposite directions.

Double white lines... Dual carriageway (60 limit)

Grass divider... Dual Carriageway (70 limit)

Crash barrier divider... Dual Carriageway (70 limit)

Motorway is only a dual carriageway road with special rules for the types of vehicles allowed and the manouvers you're allowed to do.

One more thing, not all dual carriageways and A roads have the same access rights.

Example: cyclists may use A roads, but the A470 between merthyr and cardiff, has signs up prohibiting cyclists from using it, think it may even prohibit vehicles under 125cc.

Key thing is to just look and read signs to give yourself plenty of warning.

I get people messing this up on lessons all the time, mostly car drivers. The "dual" in dual carriageway refers to DIRECTIONS of traffic, not how many lanes there are. I have a dual carriageway near me with a concrete barrier and only one lane in that direction but it's still a Dual carriageway. If there's a "national speed limit" sign and there is some sort of reservation seperating directions of traffic, the speed limit is 70. If the 2 directions of traffic aren't seperated, whether there is one lane either way or 50 lanes (exaggeration there) , it's a 60 limit only. So, bottom line, a Motorway IS a dual carriageway, the only differences being there are blue signs, an "M" somewhere on the road name and certain users are not allowed on it (read the highway code)

Hope this clears it up.

White lines don't depict a Dual carriageway, a central reservation or barrier does. If it's just white lines in the middle it's a single carriageway and a 60 limit.

(it's easy to get confused though, there are so many different rules) :-)
 
Edit: just checked the tome of all knowledge that is wikipedia, appears roadcraft nottingham is correct! It only applies to physically separated carriageways :)

Not always, the duel carriageway near me goes to 3 lanes each way for a while... I am just confusing things here aren't I?

Usually (not always) a motorway will have a full hard shoulder wide enough for a lorry to stop in, whereas a duel carriageway will have a narrower one that you can just about fit a bike on.

If in doubt and you are planning your route, look on google maps. Blue roads with starting with an M are motorways, green roads starting with an A are duel carriageway

Although, it seems its already all been covered
 
Prohibited vehicles. Motorways MUST NOT be used by pedestrians, holders of provisional motorcycle or car licences, riders of motorcycles under 50 cc, cyclists, horse riders, certain slow-moving vehicles and those carrying oversized loads (except by special permission), agricultural vehicles, and powered wheelchairs/powered mobility scooters (see Rules 36-46 incl).

[Laws HA 1980 sects 16, 17 & sch 4, MT(E&W)R regs 3(d), 4 & 11, MT(E&W)(A)R, R(S)A sects 7, 8 & sch 3, RTRA sects 17(2) & (3), & MT(S)R reg 10]

Rule 254

Traffic on motorways usually travels faster than on other roads, so you have less time to react. It is especially important to use your mirrors earlier and look much further ahead than you would on other roads.

Motorway signals
Rule 255

Motorway signals (see 'Light signals controlling traffic') are used to warn you of a danger ahead. For example, there may be an incident, fog, a spillage or road workers on the carriageway which you may not immediately be able to see.

Rule 256

Signals situated on the central reservation apply to all lanes. On very busy stretches, signals may be overhead with a separate signal for each lane.

Rule 257

Amber flashing lights. These warn of a hazard ahead. The signal may show a temporary maximum speed limit, lanes that are closed or a message such as 'Fog'. Adjust your speed and look out for the danger until you pass a signal which is not flashing or one that gives the 'All clear' sign and you are sure it is safe to increase your speed.

Rule 258

Red flashing lights. If red lights on the overhead signals flash above your lane and a red 'X' is showing, you MUST NOT go beyond the signal in that lane. If red lights flash on a signal in the central reservation or at the side of the road, you MUST NOT go beyond the signal in any lane.

[Laws RTA 1988 sect 36 & TSRGD regs 10 & 38]

Rule 259

Joining the motorway. When you join the motorway you will normally approach it from a road on the left (a slip road) or from an adjoining motorway. You should

Give priority to traffic already on the motorway
Check the traffic on the motorway and match your speed to fit safely into the traffic flow in the left-hand lane
Not cross solid white lines that separate lanes or use the hard shoulder
Stay on the slip road if it continues as an extra lane on the motorway
Remain in the left-hand lane long enough to adjust to the speed of traffic before considering overtaking


On the motorway
Rule 260

When you can see well ahead and the road conditions are good, you should

Drive at a steady cruising speed which you and your vehicle can handle safely and is within the speed limit (see Rule 124)
Keep a safe distance from the vehicle in front and increase the gap on wet or icy roads, or in fog (see Rules 126 and 235)


Rule 261

You MUST NOT exceed 70 mph (112 km/h), or the maximum speed limit permitted for your vehicle (see Rule 124). If a lower speed limit is in force, either permanently or temporarily, at road works for example, you MUST NOT exceed the lower limit. On some motorways, mandatory motorway signals (which display the speed within a red ring) are used to vary the maximum speed limit to improve traffic flow. You MUST NOT exceed this speed limit.

[Law RTRA sects 17, 86, 89 & sch 6]

Rule 262

The monotony of driving on a motorway can make you feel sleepy. To minimise the risk, follow the advice in Rule 91.

Rule 263

You MUST NOT reverse, cross the central reservation, or drive against the traffic flow. If you have missed your exit, or have taken the wrong route, carry on to the next exit.

[Laws MT(E&W)R regs 6, 8 & 10 & MT(S)R regs 4, 5, 7 & 9]

Lane discipline
Rule 264

You should always drive in the left-hand lane when the road ahead is clear. If you are overtaking a number of slower-moving vehicles, you should return to the left-hand lane as soon as you are safely past. Slow-moving or speed-restricted vehicles should always remain in the left-hand lane of the carriageway unless overtaking. You MUST NOT drive on the hard shoulder except in an emergency or if directed to do so by the police, HA traffic officers in uniform or by signs.

[Laws MT(E&W)R regs 5, 9 & 16(1)(a), MT(S)R regs 4, 8 & 14(1)(a), and RTA 1988, sects 35 & 186, as amended by TMA 2004 sect 6]

Rule 265

The right-hand lane of a motorway with three or more lanes MUST NOT be used (except in prescribed circumstances) if you are driving

Any vehicle drawing a trailer
A goods vehicle with a maximum laden weight exceeding 3.5 tonnes but not exceeding 7.5 tonnes, which is required to be fitted with a speed limiter
A goods vehicle with a maximum laden weight exceeding 7.5 tonnes
A passenger vehicle with a maximum laden weight exceeding 7.5 tonnes constructed or adapted to carry more than eight seated passengers in addition to the driver
A passenger vehicle with a maximum laden weight not exceeding 7.5 tonnes which is constructed or adapted to carry more than eight seated passengers in addition to the driver, which is required to be fitted with a speed limiter

[Laws MT(E&W)R reg 12, MT(E&W)AR (2004), MT(S)R reg 11 & MT(S)AR (2004)]

Rule 266

Approaching a junction. Look well ahead for signals or signs. Direction signs may be placed over the road. If you need to change lanes, do so in good time. At some junctions a lane may lead directly off the motorway. Only get in that lane if you wish to go in the direction indicated on the overhead signs.

Overtaking
Rule 267

Do not overtake unless you are sure it is safe and legal to do so. Overtake only on the right. You should

Check your mirrors
Take time to judge the speeds correctly
Make sure that the lane you will be joining is sufficiently clear ahead and behind
Take a quick sideways glance into the blind spot area to verify the position of a vehicle that may have disappeared from your view in the mirror
Remember that traffic may be coming up behind you very quickly. Check all your mirrors carefully. Look out for motorcyclists. When it is safe to do so, signal in plenty of time, then move out
Ensure you do not cut in on the vehicle you have overtaken
Be especially careful at night and in poor visibility when it is harder to judge speed and distance


Rule 268

Do not overtake on the left or move to a lane on your left to overtake. In congested conditions, where adjacent lanes of traffic are moving at similar speeds, traffic in left-hand lanes may sometimes be moving faster than traffic to the right. In these conditions you may keep up with the traffic in your lane even if this means passing traffic in the lane to your right. Do not weave in and out of lanes to overtake.

Rule 269

Hard shoulder. You MUST NOT use the hard shoulder for overtaking. In areas where an Active Traffic Management (ATM) Scheme is in force, the hard shoulder may be used as a running lane. You will know when you can use this because a speed limit sign will be shown above all open lanes, including the hard shoulder. A red cross or blank sign above the hard shoulder means that you MUST NOT drive on the hard shoulder except in an emergency or breakdown. Emergency refuge areas have also been built into these areas for use in cases of emergency or breakdown.

[Laws MT(E&W)R regs 5, 5A & 9, MT(S)R regs 4 & 8]
Highway Code Rule 269

Stopping
Rule 270

You MUST NOT stop on the carriageway, hard shoulder, slip road, central reservation or verge except in an emergency, or when told to do so by the police, HA traffic officers in uniform, an emergency sign or by flashing red light signals. Do not stop on the hard shoulder to either make or receive mobile phone calls.

[Laws MT(E&W)R regs 5A, 7, 9, 10 & 16,MT(S)R regs 6(1), 8, 9 & 14, PRA 2002 sect 41 & sched 5(8), & RTA 1988 sects 35 & 163 as amended by TMA 2004, sect 6]

Rule 271

You MUST NOT pick up or set down anyone, or walk on a motorway, except in an emergency.

[Laws RTRA sect 17 & MT(E&W)R reg 15]

Leavin the motorway
Rule 272

Unless signs indicate that a lane leads directly off the motorway, you will normally leave the motorway by a slip road on your left. You should

Watch for the signs letting you know you are getting near your exit
Move into the left-hand lane well before reaching your exit
Signal left in good time and reduce your speed on the slip road as necessary


Rule 273

On leaving the motorway or using a link road between motorways, your speed may be higher than you realise - 50 mph may feel like 30 mph. Check your speedometer and adjust your speed accordingly. Some slip-roads and link roads have sharp bends, so you will need to slow down.
 
I read this thread this morning just before I went out so I decided to see if I could aid you in any way.
