CDL school covers regulations and basic operation. It rarely covers the specific habits that separate drivers who retire healthy from drivers who don’t. Truck driving has fatality and injury rates among the highest of any US occupation. Most career-ending incidents trace back to a small set of preventable mistakes.
Pre-trip – non-negotiable
1. Don’t skip the pre-trip inspection
FMCSA requires it; smart drivers actually do it. The pre-trip catches mechanical issues that cause crashes: low tire pressure, brake light failure, loose lugs, hydraulic leaks. Cutting pre-trip to 30 seconds costs careers.
2. Check ELD and hours before rolling
Hours-of-service violations bring CSA points, suspensions, and carrier penalties. Verify available drive time before accepting a load.
3. Trip-plan including fuel and rest stops
Knowing where you’ll fuel and park overnight prevents desperate “finding parking at 11 PM” scenarios that lead to over-hours and fatigue.
4. Check the load and trailer
Properly secured cargo; trailer doors closed; reefer set correctly. Improperly secured loads have killed drivers when shifting cargo destabilises the trailer.
On the road – the big risks
5. Maintain following distance
One second per 10 feet of vehicle length under 40 mph; add a second above 40. For a 70-foot tractor-trailer at highway speed: minimum 8 seconds. Most drivers follow closer; it’s the leading factor in rear-end crashes.
6. Treat tailgating as the death trap it is
Cars cut in front of you – let them. Don’t accelerate to close the gap. A loaded tractor-trailer at 65 mph takes 525-700 feet to stop in dry conditions; nearly double in wet.
7. Mind the blind spots – yours and others
Trucks have four major blind spots:
- Directly in front – within 20 feet of the bumper
- Directly behind – within 30 feet of the trailer
- Left side – about one lane wide
- Right side – two lanes wide, the most dangerous
Check mirrors every 5-10 seconds.
8. Use jake brake / engine brake on grades
Long downhill braking on service brakes alone overheats them to failure. Lost-brakes scenarios on mountain grades have killed many drivers. Downshift early, save service brakes for slowing and stopping.
Fatigue management
9. Get real sleep, not the legal minimum
Hours-of-service requires 10 hours off, but counts “off” time, not sleep time. Drivers who get 5-6 hours of actual sleep crash significantly more. Studies show drivers running on 6 hours sleep are functionally as impaired as drivers at 0.08% BAC.
10. Recognise micro-sleeps
Heavy eyelids, blank stares, missing exits, hitting rumble strips. Any of these means pull over now. Coffee, loud music, and windows down don’t fix fatigue – sleep does.
11. Don’t drive on the back end of hours
Pushing into hour 10-11 of drive time, especially after midnight, is when most fatigue crashes happen. Pre-trip planning that lets you stop with hours left is safer.
Weather and conditions
12. Know when not to drive
Black ice, severe blizzard, blinding fog, flood-stage rain. The carrier’s pressure to deliver doesn’t beat dying. FMCSA explicitly allows drivers to shut down for unsafe conditions.
13. Crosswinds and high-profile cargo
Empty trailers blow over more easily than loaded. Avoid bridges and open valleys in severe wind.
14. Snow and ice = slow down dramatically
Stopping distance can triple on ice. Truck momentum makes jack-knife crashes likely on icy descents. Drop highway speed to 35-45 mph or less.
Parking and stopping
15. Don’t park on highway shoulders unless emergency
Drowsy car drivers gravitate toward truck lights. Multiple fatality crashes happen yearly when a car drifts into a parked truck. Use rest areas, truck stops, or exits.
16. Use triangles correctly when you must stop
Three reflective triangles spaced per FMCSA: 10 feet, 100 feet, 200 feet behind the vehicle.
Health for the long career
17. Sleep apnea – get tested
Massively overrepresented among truck drivers. Untreated sleep apnea has been implicated in fatal crashes. If you snore loudly or wake up tired, get tested.
18. Move every day – even briefly
10 minutes of walking at every fuel/meal stop. Long-term truck driver health correlates strongly with obesity, diabetes, and heart disease. The job actively undermines health; deliberately move.
Bottom line
Pre-trip every time, following distance to safety not convenience, blind-spot awareness, fatigue management, weather sense, parking safely, and personal health. The drivers who retire healthy after 30+ years aren’t the fastest; they’re the most consistent on the basics. Verify specific regulations with FMCSA (US), DVSA (UK), NHVR (Australia), or your local commercial vehicle authority.
