A loaded truck has many times the mass of a car and far less grip in reserve. When conditions turn, the gap between an experienced driver and a new one shows up immediately. Here is what changes and what to do about it.
The first rain after a dry spell is the worst
Oil, rubber and diesel residue sit on the road surface until rain lifts them into a slick film. That first period — before sustained rain washes the surface — is when grip is lowest.
- Increase your following distance well beyond what feels necessary
- Brake earlier and more gently; sudden pedal input can lock a drive axle
- Avoid the polished wheel tracks in each lane where water pools first
Aquaplaning starts lower than most drivers think
Worn tread and under-inflation drop the threshold significantly. If the steering suddenly goes light, do not brake and do not steer hard. Ease off, hold the wheel straight, and let the tyres find the surface again.
Your tyres are the only thing connecting you to the road. Tread and pressure checks are not paperwork — they are the difference between stopping and sliding.
Crosswinds and the empty trailer problem
An empty or lightly loaded high-sided body is far more vulnerable to wind than a fully loaded one. Gusts hit hardest when you leave shelter — clearing a cutting, passing a bridge parapet, or coming out from behind another truck.
- Anticipate the exposed point and reduce speed before you reach it
- Hold the wheel firmly with both hands but resist over-correcting afterwards
- If the gusts exceed your comfort level, stop. No delivery window is worth a rollover
Dawn, dusk and low sun
Low sun is genuinely dangerous in a truck because you sit high and the visor rarely covers it. Keep the inside of the windscreen clean — film that is invisible at midday turns into a wall of glare at sunrise. Slow down and increase your gap rather than squinting through it.
Reduced visibility: be seen first
In heavy rain, fog or dust, headlights do far more to make you visible than to help you see. Increase the gap, use the left line marking as your reference rather than the vehicle ahead, and if you must stop, get completely off the carriageway.
The habit that covers all of it
Look further ahead than feels natural. A long visual lead gives you time to recognise a hazard, decide, and act smoothly instead of reacting. Everything else in defensive driving flows from seeing the problem early enough to solve it gently.
Our lessons include wet-weather and low-light driving wherever conditions allow, because that is when judgement matters most. See our courses.
