Hazard Detection
|
General Statistics
- The three-second sequence: Within a one-second window a driver scans for a hazard then has 2 seconds to detect and recognize it, and then decide how to respond in order to avoid or lessen the severity of a crash.1
- Because their search skills are underdeveloped, new drivers often detect a hazard later than experienced drivers, increasing crash risk. 1
- Among crashes attributed to a critical teen driver error, 21 percent were due to lack of scanning that is needed to detect and respond to hazards. 2
- Although current Graduated Driver Licensing (GDL) laws help reduce teen driver crash rates by limiting the number of peer passengers and banning in-car cell phone use, many crashes will still occur due to the inability of teen drivers to detect and respond to a hazard in time. 2
- Even in young adults with an average four years of driving experience, mind wandering while driving is associated with a tendency to scan the environment more narrowly. 3
