ACT knowledge test roundabouts practice questions

Question 1

You are approaching a roundabout. Who must you give way to?

• Only vehicles entering from your right
• Only vehicles indicating to leave
• Any vehicle already in the roundaboutCorrect answer
• Only larger vehicles such as buses and trucks

The rule is give way to any vehicle already travelling in the roundabout, no matter which entry it used. Slow on approach so you can stop if there is no gap.

Question 2

You are turning left at a roundabout. Which signal do you use on approach?

• A left signal on approach and through the roundaboutCorrect answer
• No signal is needed for a left turn
• A right signal until you reach your exit
• Hazard lights while in the roundabout

For a left turn you signal left before you enter and keep it on until you have left the roundabout. Use the left lane unless signs or arrows say otherwise.

Question 3

You are turning right at a roundabout. What is the correct signalling sequence?

• No signal on approach, right before you exit
• Left on approach, then right before you exit
• Right on approach only, with no exit signal
• Right on approach, then left before you exitCorrect answer

Signal right as you approach and while you travel around, then change to a left signal once you pass the exit before the one you want. Turn the signal off after you are out.

Question 4

You are going straight ahead through a roundabout. What should you do about signalling?

• Signal right on approach, then left to exit
• Signal left on approach, then right to exit
• No approach signal, but signal left before you exit if practicableCorrect answer
• Signal is not required at any point

Going straight ahead needs no signal on the way in, but you should signal left before leaving so drivers waiting to enter know you are getting off.

Question 5

At a multi lane roundabout, which lane should you normally use to turn right?

• The left lane, then cut across
• The right lane, unless signs or arrows say otherwiseCorrect answer
• Whichever lane has the shortest queue
• The centre of the road, straddling both lanes

A right turn is made from the right lane. Road markings and arrows on the approach override the general rule, so read them before you commit.

Question 6

You are in the left lane of a two lane roundabout and a car is beside you in the right lane. What should you do?

• Speed up so you are ahead before the exit
• Move into the right lane to keep clear
• Sound your horn to claim your lane
• Stay in your lane and let the other driver take theirsCorrect answer

Hold your marked lane the whole way through a roundabout. Changing lanes inside a roundabout is where most side to side collisions there happen.

Question 7

A cyclist is riding in the left lane of a roundabout and is signalling right to continue around. What should you do?

• Give way and let the cyclist continue aroundCorrect answer
• Overtake on the right and exit ahead
• Move alongside so you can exit together
• Expect the cyclist to leave at the next exit

Bicycle riders are allowed to stay in the left lane while travelling right around a roundabout, and they must signal their intention. Hang back rather than squeezing past.

Question 8

You are entering a small single lane roundabout and it is completely clear. What must you still do?

• Stop fully at the holding line
• Sound the horn before entering
• Slow down enough to give way if a vehicle appearsCorrect answer
• Enter at the posted limit without slowing

A roundabout carries a give way requirement, not a stop requirement. You do not have to stop when it is clear, but you must approach at a speed that lets you give way if something arrives.

Question 9

You have entered a roundabout and realise you want a later exit than planned. What is the safest action?

• Brake hard and reverse to the earlier exit
• Stop in the roundabout and wait for a gap
• Cross lanes immediately to reach the exit
• Continue around and take a later exit or come backCorrect answer

Never stop or reverse inside a roundabout. Keep circulating in your lane, leave at a safe exit, and turn around further along the road.
