Theory Test - Rules of The Road Category

Topics include:

  • Speed Limits - Knowing the different speed limits and when to use these speed limits.

  • Lighting - using car lighting effectively and safely to see and be seen when driving.

  • Lane Discipline - know and understanding lane rule regulations.

  • Parking - where to safely park and knowing the different parking restrictions and regulations.

Again, safety is a theme that dominates many questions.

Many questions present every day road situations where the correct answer is always the safest options, for example:
You are on a busy main road and find that you are travelling in the wrong direction. What should you do?
  1. Turn into a side road on the right and reverse into the main road
  2. make a U-turn in the main road
  3. Make a 'three-point' turn in the main road
  4. Turn round in a side road

The correct answer, the safest, is 4. No question will require an answer such as 'speed up', 'sound your horn' or 'flash your lights'

Facts to Know

  • The national speed limit for cars and motorcycles on single carriageway roads is 60 mph.

  • The national speed limit for cars and motorcycles on motorways and dual carriageways is 70 mph.

  • The speed limit for cars towing a trailer on single carriageway roads is 50 mph.

  • The speed limit for cars towing a small caravan on motorways and dual carriageways is 60 mph.

  • On a road with street lights, but no speed limit signs, the speed limit is usually 30 mph.

  • At an unmarked crossroads no one has priority.

  • The nearest you can park to a junction is 10 metres (32 feet).

  • You may drive over a footpath to get to a property.

  • You must not drive in a cycle lane marked by a solid white line during its period of operation.

  • A cycle lane marked by a broken white line means you should not drive in, or park in the lane unless it is unavoidable.

  • You must not drive in a bus lane during its hours of operation. The hours of operation will be marked on the bus lane road sign.

  • You can only stop on an urban clearway to set down and pick up passengers.

  • When waiting at a level crossing if the red lights continue to flash after a train has passed you must continue to wait.

  • Never park in an disabled only parking space unless permitted i.e. you are a blue badge holder.

  • If a car overtakes you at night and you have your headlights on full beam you should switch them to dipped as soon as the vehicle passes you.

  • Zebra Crossing - if someone is waiting to cross you should stop and let them cross.

  • Toucan Crossings - can be use by cyclists and pedestrians.

  • Pelican Crossings - a flashing amber light means you must give way to pedestrians still crossing. If the light changes to red and people are still crossing then you must continue to wait and let them cross

  • You can only drive in a bus lane outside its hours of operation.

Box Junctions

  • You may only wait in a box junction when you're turning right and your exit lane is clear but you can't complete the turn because of oncoming traffic. Box Junctions Video Tutorial.

Parking At Night

  • If you park at night on a road where the speed limit is above 30 mph you must leave your parking lights (sidelights) on.
  • Always park facing the flow of traffic

Where Not to Park

  • On the pavement
  • At a bus stop
  • In front of someone's drive
  • Opposite a traffic island
  • Near a school entrance
  • On a pedestrian crossing (or inside the zigzag lines either side of it)
  • Near a junction
  • On a clearway
  • On a motorway


  • Going left - signal left as you approach the roundabout. Keep signalling until you have left the roundabout.
  • Going straight ahead - signal left just after you pass the exit before the one you will take.
  • Going right - signal right as you approach the roundabout. Signal left just after you pass the exit before the one you will take. Roundabouts Video Tutorial.


  • You must not reverse for longer than is necessary.
  • Never reverse from a side road onto a main road
  • When reversing into a side road, the main hazard to oncoming traffic, is when the front of your vehicle swings out.

DSA Theory Test Questions - Rules of The Road
1 There is a tractor ahead of you. You wish to overtake but you are not sure if it is safe to do so. You should

Mark one answer.

Knowledge and UnderstandingNever overtake if you’re not sure whether it’s safe. Can you see far enough down the road to ensure that you can complete the manoeuvre safely? If the answer is no, DON’T GO.

follow another overtaking vehicle through
sound your horn to the slow vehicle to pull over
speed through but flash your lights to oncoming traffic
not overtake if you are in doubt
2 Which THREE of the following are most likely to take an unusual course at roundabouts?

Mark THREE answers.

Knowledge and UnderstandingLong vehicles might have to take a slightly different position when approaching the roundabout or going around it. This is to stop the rear of the vehicle cutting in and mounting the kerb. Horse riders and cyclists might stay in the left-hand lane although they are turning right. Be aware of this and allow them room.

Horse riders
Milk floats
Delivery vans
Long vehicles
Estate cars
3 On a clearway you must not stop

Mark one answer.

Knowledge and UnderstandingClearways are in place so that traffic can flow without the obstruction of parked vehicles. Just one parked vehicle will cause an obstruction for all other traffic. You MUST NOT stop where a clearway is in force, not even to pick up or set down passengers.

at any time
when it is busy
in the rush hour
during daylight hours
4 You can park on the right-hand side of a road at night

Mark one answer.

Knowledge and UnderstandingRed rear reflectors show up when headlights shine on them. These are useful when you are parked at night but will only reflect if you park in the same direction as the traffic flow. Normally you should park on the left, but if you’re in a one-way street you may also park on the right-hand side.

in a one-way street
with your sidelights on
more than 10 metres (32 feet) from a junction
under a lamp-post
5 You are approaching a busy junction. There are several lanes with road markings. At the last moment you realise that you are in the wrong lane. You should

Mark one answer.

Knowledge and UnderstandingThere are times where road markings can be obscured by queuing traffic, or you might be unsure which lane you need to be in. If you realise that you’re in the wrong lane, don’t cut across lanes or bully other drivers to let you in. Follow the lane you’re in and find somewhere safe to turn around if you need to.

continue it that lane
force your way across
stop until the area has cleared
use clear arm signals to cut across
6 Where may you overtake on a one-way street?

Mark one answer.

Knowledge and UnderstandingYou can overtake other traffic on either side when travelling in a one-way street. Make full use of your mirrors and ensure that it’s clear all around before you attempt to overtake. Look for signs and road markings and use the most suitable lane for your destination.

Only on the left-hand side
Overtaking is not allowed
Only on the right-hand side
Either on the right or the left
7 When going straight ahead at a roundabout you should

Mark one answer.

Knowledge and UnderstandingWhen you want to go straight on at a roundabout, don’t signal as you approach it, but indicate left just after you pass the exit before the one you wish to take.

indicate left before leaving the roundabout
not indicate at any time
indicate right when approaching the roundabout
indicate left when approaching the roundabout
8 Which vehicle might have to use a different course to normal at roundabouts?

Mark one answer.

Knowledge and UnderstandingA long vehicle may have to straddle lanes either on or approaching a roundabout so that the rear wheels don’t cut in over the kerb. If you’re following a long vehicle, stay well back and give it plenty of room.

Sports car
Estate car
Long vehicle
9 You must stop when signalled to do so by which THREE of these?

Mark THREE answers.

Knowledge and UnderstandingLooking well ahead and ‘reading’ the road will help you to anticipate hazards. This will enable you to stop safely at traffic lights or if ordered to do so by an authorised person.

A police officer
A pedestrian
A school crossing patrol
A bus driver
A red traffic light
10 You are intending to turn right at a crossroads. An oncoming driver is also turning right. It will normally be safer to

Mark one answer.

Knowledge and UnderstandingAt some junctions the layout may make it difficult to turn offside to offside. If this is the case, be prepared to pass nearside to nearside, but take extra care as your view ahead will be obscured by the vehicle turning in front of you.

keep the other vehicle to your RIGHT and turn behind it (offside to offside)
keep the other vehicle to your LEFT and turn in front of it (nearside to nearside)
carry on and turn at the next junction instead
hold back and wait for the other driver to turn first
11 You meet an obstruction on your side of the road. You should

Mark one answer.

Knowledge and UnderstandingTake care if you have to pass a parked vehicle on your side of the road. Give way to oncoming traffic if there isn’t enough room for you both to continue safely.

carry on, you have priority
give way to oncoming traffic
wave oncoming vehicles through
accelerate to get past first
12 Which THREE places must you not park?

Mark THREE answers.

Knowledge and UnderstandingOther traffic will have to pull out to pass you. They may have to use the other side of the road, and if you park near the brow of a hill, they may not be able to see oncoming traffic. It’s important not to park at or near a bus stop as this could inconvenience passengers, and may put them at risk as they get on or off the bus. Parking near a junction could restrict the view for emerging vehicles.

Near the brow of a hill
At or near a bus stop
Where there is no pavement
Within 10 metres (32 feet) of a junction
On a 40 mph road
13 You are travelling on a well-lit road at night in a built-up area. By using dipped headlights you will be able to

Mark one answer.

Knowledge and UnderstandingYou may be difficult to see when you’re travelling at night, even on a well lit road. If you use dipped headlights rather than sidelights other road users will see you more easily.

see further along the road
go at a much faster speed
switch to main beam quickly
be easily seen by others
14 When you are not sure that it is safe to reverse your vehicle you should

Mark one answer.

Knowledge and UnderstandingIf you can’t see all around your vehicle get out and have a look. You could also ask someone reliable outside the vehicle to guide you. A small child could easily be hidden directly behind you. Don’t take risks.

use your horn
rev your engine
get out and check
reverse slowly
15 When may you reverse from a side road into a main road?

Mark one answer.

Knowledge and UnderstandingDon’t reverse into a main road from a side road. The main road is likely to be busy and the traffic on it moving quickly. Cut down the risks by reversing into a quiet side road.

Only if both roads are clear of traffic
Not at any time
At any time
Only if the main road is clear of traffic
