California DMV Motorcycle Knowledge Test (M1)Lane Position and VisibilityHard
When riding in city traffic, you notice a delivery truck parked just ahead, partially blocking your lane, with its hazard lights on. What is the most appropriate lane positioning and scanning strategy as you approach this obstruction?
- ASlow down, scan for hazards around and beyond the truck, and be prepared to adjust your path and speed.
- BSlow down and move immediately to the far left of your lane to pass the truck.
- CMaintain speed, but scan for pedestrians or vehicle doors opening from behind the truck.
- DAccelerate slightly to quickly clear the truck's area before any new hazards emerge.
Show answer & explanationAnswer & explanation
Correct answer: A. Slow down, scan for hazards around and beyond the truck, and be prepared to adjust your path and speed.
A parked delivery truck, especially with hazard lights, indicates potential activity (people, open doors, other vehicles). Slowing down provides more time to react, and extensive scanning allows you to anticipate and prepare for multiple hidden hazards that might emerge from around or behind the truck.
Why the other options are wrong
- B. Moving immediately left without proper scanning could put you into the path of oncoming traffic or another lane's blind spot.
- C. Maintaining speed reduces reaction time, making it harder to respond to unexpected hazards.
- D. Accelerating reduces your reaction time and increases the risk if a pedestrian steps out or a door opens unexpectedly.
Hazard Zone Scanning
A systematic approach to scanning for potential dangers around stationary or slow-moving obstacles that might obscure hazards.
- Look for pedestrians, opening doors, vehicles moving out.
- Scan beyond the immediate obstruction.
- Reduce speed to increase reaction time.
Memory trick: Slow, scan, survive the unseen.
