A 22-year-old Ottawa man is dead after a high speed crash on Prince of Wales Drive in rural south Ottawa.

The crash happened just before 2:30 p.m. Thursday.

Witnesses said the man was naked behind the wheel, speeding and passed six vehicles before crossing the centre line and slamming into four RV trailers near the Car Canada dealership.

The driver was pronounced dead at the scene and was not wearing his seatbelt, according to police.

Prince of Wales between William McEwen Drive and Carsonby Road West was closed for 5 hours as police investigated but has since reopened.
