Safe Driving Practices and Speed Management
Speed and following distance
The exam tests whether you can choose a safe speed for conditions, maintain space, and use mirrors and lights correctly. The posted limit is a maximum, not a guarantee.
Core rules
- Obey school-zone and posted limits. Reduce speed for rain, snow, ice, fog, darkness, curves, and heavy traffic.
- Use at least a four-second following distance in good conditions; add more time when loaded, wet, or icy.
- Check mirrors systematically and before every lane change, stop, and turn. Know the blind spots around the bus.
- Activate warning lights and stop arm only as required for loading and unloading. Do not use them for parking or convenience.
- Avoid distractions. A school bus driver should not use a hand-held phone while driving.
A bus is traveling 40 mph in rain and following a car at two seconds. Reasoning: rain increases stopping distance and reduces tire grip. The driver should slow down and open the gap to four or more seconds. The posted limit does not make two seconds safe. The driver should also check mirrors and avoid a sudden brake that could cause a rear-end crash.
Traps that cost marks
Assuming the posted speed is always safe, tailgating to keep schedule, checking mirrors only at stops, and using warning lights when not loading. The exam also penalizes failure to adjust speed before a curve or downgrade.
