Used car test drive checklist

A test drive is where mechanical faults that don't show up on a static inspection tend to surface. Doing it properly means covering a mix of road types and speeds, not just a five-minute loop around the block. This checklist sets out what to test, in what order, and what each symptom might mean.

Written by the VehicleFaults Research Team

1. Before you start the engine

A few checks before moving reveal issues that a warm engine can hide later in the drive.

Start the engine from cold and listen for rattles, knocks or excessive smoke on start-up
Check the exhaust for blue smoke (oil burning), white smoke (possible head gasket issue) or thick black smoke
Let the engine idle and check it doesn't stall, surge or run roughly
Check all mirrors and the seat adjust properly before setting off
Note the fuel and temperature gauges are behaving normally as the engine warms

2. Steering, suspension and handling

Test on a road with a few bends and, ideally, some poor surface to expose play or knocking that a smooth road won't reveal.

Check the steering returns to centre smoothly after a turn, without pulling to one side
Listen for clunks over speed bumps or potholes, which can indicate worn bushes or anti-roll bar links
Brake gently at low speed and check the car doesn't pull left or right
At a safe stop, turn the wheel lock to lock and listen for any knocking or whining from the power steering
Feel for vibration through the steering wheel at motorway speed, which can suggest wheel balance or alignment issues

3. Gearbox and clutch

Manual and automatic gearboxes fail differently, so tailor the checks to the transmission type.

On a manual, check the clutch bites smoothly and not right at the top or bottom of the pedal travel
Listen for grinding or crunching when changing gear, especially into reverse
On an automatic, check gear changes are smooth without hesitation, flaring or a delayed kick-down
Check for a burning smell after several gear changes, which can indicate clutch or transmission fluid wear
Try hill starts if possible to check the clutch and handbrake hold properly

4. Braking performance

Brakes are a safety-critical item and one of the more expensive things to get wrong, with discs and pads typically costing £150-£400 per axle to replace.

Perform a firm brake test at a safe, low speed and check the car stops in a straight line without pulling
Listen for grinding, which usually means the pads have worn through to the backing plate
Check the brake pedal feels firm, not spongy, which could indicate air in the system or a master cylinder fault
Test the handbrake holds the car on a slight incline
Check the ABS warning light doesn't stay illuminated after starting

5. Noise, vibration and electrics on the move

A longer stretch of driving, ideally including some motorway or dual carriageway, exposes issues that short drives miss.

Turn off the radio and listen for wind noise, rattles or exhaust drone at a steady speed
Check the air conditioning cools properly and the heater produces hot air promptly
Test cruise control, parking sensors and any driver assistance features if fitted
Check the dashboard for warning lights appearing during the drive, particularly engine management or ABS
Listen for wheel bearing noise, a droning sound that increases with speed and changes when weaving gently

Frequently asked questions

How long should a used car test drive be?

Aim for at least 20-30 minutes covering a mix of roads: slow residential streets, a bendy road, and if possible a short stretch of dual carriageway or motorway. A drive around the block alone won't reveal gearbox, bearing or motorway-speed vibration issues.

What noises should worry me on a test drive?

Grinding when braking, knocking over bumps, whining that changes with road speed (often a wheel bearing), and clunks when changing gear are all worth investigating further. Any smell of burning clutch or a persistent knock from the engine bay is reason to pause the purchase.

Can I test drive a private sale car without insurance?

You need valid insurance to drive on the road, and a private seller's own policy usually won't cover you. Many buyers arrange short-term or day insurance in advance, or check whether their own policy includes driving other cars cover, which is increasingly rare and often third-party only.

What should I check when the car is stationary during a test drive?

Use a stop, such as a quiet junction or car park, to test the handbrake on a slope, cycle through the gears while stationary, and check all warning lights clear after start-up. It's also a good moment to check parking sensors, cameras and infotainment pairing.

Is it normal for a dealer to come on the test drive?

Yes, it's standard practice for a dealer or their representative to accompany you, partly for insurance reasons and partly to answer questions. A private seller may also want to come along, which is reasonable, but you should still be the one driving.
