Safe Driving Practices for Passenger Vehicles: Speed, Space, Turns, and Railroad Crossings
What the exam tests
This domain tests judgment about speed, following distance, lane position, turning geometry, and mandatory railroad crossing stops with passengers aboard.
Core rules
- Drive at a speed that lets you stop safely for hazards, passengers standing or moving, and reduced traction. Slow down before curves, ramps, tunnels, and work zones. Passenger comfort matters, but safety controls.
- Maintain a safe following distance. Use at least 4 seconds at normal highway speeds and add more in rain, darkness, or heavy traffic. Buses need longer stopping distances.
- Use mirrors and check blind spots. When turning, swing wide enough to keep rear wheels from cutting the corner or striking a curb. Watch tail swing.
- Buses carrying passengers must stop at railroad crossings unless the crossing is exempt. Stop 15 to 50 feet from the nearest rail, open a door or window, look and listen, and cross only when clear. Do not stop on tracks.
- Obey posted weight and height limits and know your clearance.
Worked example
A motorcoach approaches a rural crossing with crossbucks but no gates. The driver stops 20 feet before the nearest rail, opens the door, listens, looks both ways, and confirms the tracks are clear before crossing. The stop is required because passengers are aboard.
Traps
Rolling through a railroad crossing because signals are absent. Stopping too close to the rail. Turning too sharply and clipping a curb. Following a large vehicle too closely and losing sight of the road ahead.
