Safe Driving Practices, Sharing the Road, and Hazard Awareness
Domain 3 tests judgment rather than memorization: following distance, crosswalk rules, school buses, bicycles and mopeds, emergency vehicles, and hazard recognition in rain, at night, and in work zones.
Space and speed
Use the three-second rule in good conditions. Pick a fixed object ahead; when the vehicle ahead passes it, count three seconds before you reach it. In rain, add at least one second, and more if visibility is poor or roads are slick. Do not overdrive your headlights at night; you must be able to stop within the distance you can see. Slow down before curves, not during them.
Sharing the road
Pedestrians in a marked or unmarked crosswalk have the right-of-way; stop and stay stopped until they clear your path. When a school bus displays flashing red lights, stop from both directions on an undivided road. On a divided highway with a median, traffic approaching from the opposite direction is generally not required to stop, but traffic behind the bus must. Give bicyclists at least three feet when passing and do not crowd them. Mopeds and motorcycles are smaller and harder to see; check blind spots twice. Large trucks have wide turning paths and big no-zones; do not linger alongside. When an emergency vehicle approaches with lights or siren, pull to the right and stop, and follow Hawaii's move-over rule for stopped emergency and service vehicles.
Hazard awareness
Scan 12–15 seconds ahead. In work zones, reduce speed and watch for workers and narrowed lanes. Rain mixes with oil on the road surface, especially at the start of a storm. Approach railroad crossings prepared to stop. Fatigue and aggression are hazards too: pull over if drowsy, and do not engage an aggressive driver.
Worked example
You are following a large truck on a wet highway with spray limiting visibility. The three-second gap is not enough because your stopping distance is longer and the truck blocks your view. Increase to four or five seconds and move to a lane with a clearer view when safe. If you begin to hydroplane, ease off the accelerator and steer straight; do not brake hard.
Traps that cost marks
Right-of-way is something you yield, not something you take. Do not pass a stopped school bus with red lights flashing on an undivided road. Do not assume a pedestrian will wait because the light is green. A flashing red is a stop sign, not a yield sign. Keep your speed down in rain; hard braking on a slick surface invites a skid.
