The risk of crashing varies by the time of day and between weekdays and weekends. Darkness and peak drinking times combine to make late-night driving much more risky than day-time driving. The combination of alcohol and (often) higher speeds means that late night is an especially high risk time for fatal crashes. Indeed, the risk of being involved in a fatal crash is 17 times higher between 12 midnight and 3am than it is between 12 midday and 3pm.

The popular drinking nights of Thursday, Friday, and Saturday are particularly high risk times. The risk of crashing in the early hours of Sunday morning (1-3 am) is more than 20 times higher than it is on a Sunday afternoon.
