3 questions from the Ohio practice test
1. When should Ohio drivers use headlights because of weather or visibility?
- Whenever visibility is poor because of rain, snow, fog, or similar conditions
- Only when visibility falls below 100 feet
- Only after midnight during winter
- Only when another driver flashes headlights first
Show answer
Whenever visibility is poor because of rain, snow, fog, or similar conditions. Ohio requires headlights whenever visibility is poor, including conditions such as rain, snow, or fog. The rule does not wait for a particular 100 foot measurement, midnight, or another driver's signal. Headlights help the driver see and help other roadway users notice the vehicle, so the weather condition itself is the cue. The manual also requires them from sunset to sunrise and whenever windshield wipers are in use because of precipitation, making early use the safer habit.
2. Which headlights should an Ohio driver use when driving in fog?
- Low beams, not high beams
- High beams, to light the fog more strongly
- No headlights until the fog clears
- Hazard lights instead of headlights
Show answer
Low beams, not high beams. Ohio calls fog one of the most hazardous conditions a motorist can drive in. The manual tells drivers to slow down, keep a consistent distance behind the vehicle ahead, use low beam headlights rather than high beams, and keep scanning for potential hazards. Ohio also requires lights during fog regardless of the time of day, so driving without headlights until the fog clears is not an option, and hazard lights are not listed as a substitute. Shift your gaze instead of staring, and be ready to stop at any time.
3. In Ohio winter driving, which parts of the highway ice over first?
- Sunny straight stretches
- Bridges, overpasses, and shaded spots
- Toll plazas and rest areas
- Lanes next to the median
Show answer
Bridges, overpasses, and shaded spots. Ohio's winter driving section singles out three places that freeze before the rest of the highway: bridges, overpasses, and shaded spots. A road that seems fine can turn icy without warning at these spots, and a driver who carries normal speed onto them can lose traction. Slow down before you reach them, avoid sudden steering or braking on them, and keep a greater following distance because slippery roads need more room to stop.
