Gear selection influences vehicle control, engine load and fuel consumption. Driving in too high a gear at low speed can cause strain and poor response, while driving in too low a gear at high speed increases engine revs and fuel use. K53 assessment includes appropriate vehicle control. Select gears to match your speed and the road situation. Use lower gears for climbing, overtaking or navigating hazards. Use higher gears for steady cruising where the engine is not strained. Avoid coasting in neutral and avoid “fighting” the engine in an incorrect gear. Good gear selection makes driving smoother, reduces wear and improves efficiency. Practise recognising when the engine feels comfortable versus strained, and adjust gears accordingly.

Frequently Asked Questions
What happens if I drive in too high a gear?
The engine can strain, response becomes poor and you may risk stalling when slowing.
What happens if I drive in too low a gear?
Engine revs become unnecessarily high, increasing noise, wear and fuel consumption.
How do I know the correct gear?
Choose a gear where the engine feels comfortable for your speed and the road demand.
Does gear selection affect fuel use?
Yes. Appropriate gears improve fuel efficiency and reduce engine strain.
