Safe Driving Practices
What this domain covers
Safe Driving Practices tests hazard recognition and space management: following distance, speed for conditions, weather handling, distraction, fatigue, occupant protection, and sharing the road with trucks, motorcycles, cyclists, and pedestrians.
Managing space and speed
Use the three-second rule, and four or more seconds in rain, at night, or behind a large truck. Keep out of blind spots; if you cannot see a truck driver's mirror, they cannot see you. Always leave an escape path. In rain, slow down before the wipers' first swipe. If you hydroplane, ease off the accelerator, hold the wheel straight, and avoid hard braking until the tires regain contact. In fog, use low beams - high beams reflect back and cut visibility. On ice, bridges and overpasses freeze first; make every input gentle.
Distraction and fatigue
Delaware bans handheld cell phone use while driving as a primary offense, and texting is illegal for all drivers. Drivers under 18 with a permit or probationary license may not use any cell phone, even hands-free. Fatigue produces microsleeps and delayed reactions; the fix is to stop and rest, not to turn up the radio. Pull over to text or adjust navigation.
Occupant protection and sharing the road
Seat belt use is primary enforcement. In Delaware, children under 8 and under 65 pounds must be in an appropriate child restraint, and children under 2 must ride rear-facing. All occupants under 18 must be belted in any seat. Move over one lane, or slow down if you cannot, for police, fire, ambulances, tow trucks, and highway workers with lights. Give cyclists at least three feet and pedestrians in a crosswalk the right of way.
Worked example
You are driving at highway speed in heavy rain when the steering suddenly feels light and the engine revs. What do you do? That is hydroplaning. Lift off the gas smoothly so the tires slow and the water clears; do not brake hard or jerk the wheel, which can spin the car. Once grip returns, reduce speed and lengthen your following distance. Cruise control should be off in rain for exactly this reason.
Traps
Using high beams in fog; braking hard in a hydroplane; relying on all-wheel drive for grip on ice; assuming a seat belt is only required in front; passing a stopped school bus because you are in a hurry; and passing a tow truck without moving over.
