BDifficulty 2/5

Do fatigue, alcohol and adverse weather conditions affect road accidents?

Correct answer

Yes, they can increase crash risk.

Yes, they can increase risk. Fatigue reduces attention and can increase reaction time; alcohol impairs coordination, judgement and perception; rain, snow or fog can reduce grip or visibility. Effects depend on circumstances and do not predict a particular crash. Avoid driving while fatigued or after drinking, and adapt speed and gap to conditions.
