Local and state agencies are warning Clark County drivers to slow down and stay sober as the summer driving season begins — the deadliest stretch of the year.
Traffic safety officials call June, July and August the “90 Dangerous Days” because fatalities spike sharply during these months.
State records show a grim reality for summer travel.
Of the 1,584 traffic fatalities that occurred statewide in the months of June, July, and August from 2018-2025, 851 (or 54 percent) involved an impaired driver, Washington State Patrol Sgt. Jermaine Walker said in an email.
Inexperienced drivers also increase road risks during the summer. Data from AAA shows that from 2015-2024 crash fatalities involving young motorists reached 7,805 across the country during the summer months. Almost one-third of all fatal crashes involving teenagers happen between Memorial Day and Labor Day, a period the organization labels the “100 Deadliest Days.”
Summer also brings construction season and with it a higher risk of work zone crashes.
