Passing a parked car sounds simple — you've done it hundreds of times as a passenger. But on your UK driving test, failing to check your mirrors at the right moment can earn you a driving fault. Do it repeatedly, and it becomes a serious fault that means an automatic fail.
By the Numbers
Mirror faults are consistently among the top 10 most frequently recorded minor faults in UK driving tests, according to DVSA's annual driving test statistics (gov.uk/government/statistical-data-sets/car-driving-test-data-by-test-centre). With over 1.5 million car tests conducted each year, mirror-related faults affect a significant proportion of learner drivers — making mirror discipline one of the most impactful habits to build before test day.
Why Mirror Checks Matter When Passing Parked Cars
When you pass a parked car, you naturally move slightly towards the centre of the road to give it space. That outward movement is a lane change — and any lane change requires a mirror check first. Behind you, a car or motorcycle might be overtaking. A cyclist might be catching up on your left. Without checking your mirrors, you're moving into a space without knowing what's behind you.
- A car may already be overtaking you as you swing out.
- Cyclists travel faster than expected and may be in your blind spot.
- On residential streets with parking on both sides, you may need to yield to oncoming traffic.
How to Check Correctly
Before moving out around the parked car, check your interior mirror and the door mirror on the side you plan to move towards — normally the right mirror. Reassess oncoming traffic and leave enough clearance. Before moving back left, check the interior and left mirrors for cyclists or other road users on the nearside.
Practice tip
In UK residential areas, it's common to have cars parked on both sides of the road, leaving barely enough room for two vehicles to pass. When you spot this situation ahead, slow down early, check all three mirrors, and be ready to give way if a vehicle is already approaching from the opposite direction.
The Habit to Build
Treat parked cars as potential hazards. Plan early, check the mirrors relevant to each change of position, and look for occupants, opening doors, pedestrians and oncoming traffic. The checks should support a safe decision rather than follow a rigid script regardless of the road layout.
Frequently asked questions
- Do I need to check mirrors every single time I pass a parked car?
- Yes. Every time you change your lateral position on the road, a mirror check is expected. Passing a parked car is a positional change, so it requires the same discipline as a lane change.
- Which mirrors should I check?
- Check the interior mirror and the mirror in the direction you will move. When moving right around a parked car on your left, that normally means the interior and right mirrors. Check the interior and left mirrors before returning left.
- How far before the parked car should I check?
- Check your mirrors well in advance — ideally 5–6 car lengths before the obstruction — so you have time to react if something is close behind you.
