Besides a driver's natural reaction time, what does 'reaction distance' measure as part of total stopping distance?
- A. The outside air temperature
- B. The distance traveled after the brakes are fully applied
- C. The vehicle's total weight
- D. The distance traveled between noticing a hazard and braking
Show answer

What is the key problem with following too closely in stop-and-go traffic?
- A. It wastes fuel
- B. Stop-and-go requires less following distance since speeds are low
- C. You must brake harder each time the vehicle ahead does
- D. Tailgating is only dangerous above 30 mph
Show answer
C. You must brake harder each time the vehicle ahead does — Stop-and-go tailgating: each braking event requires harder response with no reaction buffer. Chain-reaction rear-end crashes are common in slow traffic. Maintain 2-3 second gaps even in slow conditions.

When approaching an intersection with a steady red light and then it changes to green, what should you do first?
- A. Honk to clear the intersection as required by traffic law
- B. Accelerate immediately since you now have the right of way
- C. Wait 3 seconds before moving as a safety rule
- D. Check that cross traffic has cleared before proceeding
Show answer
D. Check that cross traffic has cleared before proceeding — Even after a red-to-green change, check cross traffic before entering the intersection. Red-light runners are common - the most dangerous moment is often right after your light turns green when a cross-traffic vehicle is completing their run.

What is 'jaywalking' and what are the risks?
- A. Walking on a bike path
- B. Crossing the road outside a designated crosswalk or against a traffic signal
- C. Riding a bicycle on a sidewalk
- D. Walking against a WALK signal when no cars are visible
Show answer
B. Crossing the road outside a designated crosswalk or against a traffic signal — Jaywalking is crossing outside marked crosswalks or against signals. Drivers don't expect pedestrians mid-block, reducing their time to react. Jaywalking pedestrians are at far higher risk than those using legal crossings.
