- Scanning ahead
- Look 10–15 seconds down the road, check mirrors every few seconds, and keep an escape path.

- Slow down, brake and steer gently, leave extra distance, and use low beams in poor visibility.
- Stopping at a railroad crossing
- Stop at least 15 feet from the nearest rail when lights flash or a gate lowers; never go around a lowered gate.
- Why never drive around a crossing gate
- A second train may be coming on another track, and you cannot judge a train's speed accurately.
- Tailgating risk
- Following too closely leaves no room to react — most rear-end crashes come from short following distance.
- Speed and stopping distance
- Stopping distance grows sharply with speed — at higher speeds it takes much farther to stop.
- Two-second rule vs. three-second rule
- Ohio's defensive standard is at least three seconds; add more in poor conditions or behind larger vehicles.
- Driving while drowsy vs. impaired
- Both severely impair reaction and judgment; the safest choice is to stop and rest or not drive.
- Effect of alcohol on driving
- It slows reaction time, impairs judgment and coordination, and reduces vision — there is no safe amount.

- School bus yellow flashing lights
- A warning that the bus is about to stop — slow down and prepare to stop.
- Passing a stopped school bus
- A serious Ohio violation that endangers children — never pass a bus with red lights flashing.

- Turning right with a bicyclist ahead
- Yield and let the bicyclist pass through the intersection before you turn across their path.
- Sharing the road with motorcyclists
- Allow extra following distance and check blind spots — motorcycles are small and easy to miss.
- Why a motorcyclist shifts position in the lane
- Riders move to absorb or avoid hazards that barely affect cars — give them room to maneuver.
- Large truck blind spots (no-zones)
- Trucks have big blind spots on the sides, front, and rear — if you can't see the driver's mirror, they can't see you.
- Truck turning right
- A large truck may swing left first to make a right turn — never squeeze up the right side.
- Merging in front of a truck
- Trucks need much more distance to slow down — do not cut in close in front of one.
- Meeting farm equipment on a rural road
- Stay back at a safe distance and pass only on a clear, legal stretch with good visibility.
- Slow Moving Vehicle emblem meaning

- Work-zone driving
- Slow down, obey flaggers and signs, and watch for lane shifts; fines are often doubled in work zones.
