Vehicle operation, safety and risk prevention
Vehicle Operation
Controls, positioning, and the physics of stopping
Vehicle-operation questions reward precision about procedure. Teach the pre-drive routine: walk-around inspection, seat and head-restraint adjustment, mirrors set after the seat (BGE - behind, gap, edge), belt and passenger check, then start. Hands at 9 and 3 or 8 and 4 to keep arms clear of an airbag; push-pull or hand-over-hand steering as the turn demands; shuffle the wheel rather than crossing arms on recovery.
Moving off is a taught sequence: mirror, signal, mirror again, head check, ease off, then accelerate. Backing is slow speed, both hands on the wheel, turn and look, use mirrors as a supplement, and get out and look when unsure. Lane position should be deliberate - center, or offset away from oncoming traffic and parked cars.
Following distance is the three-second rule, extended to four or more in rain, at night, behind trucks, or when being tailgated. Stopping distance has three parts: perception, reaction, and braking. Braking distance grows with the square of speed - double the speed and braking distance roughly quadruples. That relationship is the most common computational trap.
Parking traps: downhill with a curb, turn the wheels toward the curb; uphill with a curb, turn them away from the curb so a roll-back catches the tire; uphill with no curb, turn toward the right edge.
Worked example: at 60 mph you travel about 88 feet per second, so a three-second gap is roughly 264 feet - nearly the length of a football field. At 30 mph, the same gap is about 132 feet. Use this to show a student why the gap is measured in time, not car lengths.
Safety and Risk Prevention
Teach the search, not the scare
Risk-prevention content is about systematic scanning and prepared responses. Use a search model such as SIPDE - Scan, Identify, Predict, Decide, Execute - or the Smith system's aim-high, get-the-big-picture, keep-your-eyes-moving structure. Students should be able to name the space cushion around the vehicle, the no-go zones beside and behind large trucks, and the escape route they would use if the hazard ahead materialized.
Cover the major risk categories: distraction (phone, passengers, food), impairment (alcohol, cannabis, prescription and over-the-counter drugs), fatigue, speed, and non-use of belts. Maryland restricts handheld phone use and prohibits texting, and drivers under 18 may not use a phone at all while driving, even hands-free. Occupant protection is primary enforcement: everyone belted, and children under 8 and under 4 feet 9 inches in an appropriate child restraint, rear-facing until at least age 2.
Weather and surface hazards: hydroplaning, skids, fog, ice, and high wind. Teach the recovery principle - look and steer where you want to go, ease off the accelerator, and avoid hard braking or abrupt steering. For a tire blowout, grip the wheel, stay off the brake, and decelerate gradually. For an animal in the road, brake firmly rather than swerve into oncoming traffic or off the shoulder.
Worked example: a student feels the wheel go light in heavy rain at 55 mph. Prompt the sequence aloud - ease off the accelerator, hold the wheel steady, no hard braking, look toward the open lane - then discuss afterwards why the speed made the hydroplane likely and what following distance would have helped.
