ABBOTSFORD Police announced at 9:38 p.m. on Monday that Highway 1 eastbound was closed at Whatcom Road after a semi-truck collision. No other vehicles were involved.

No injuries were reported. The driver of the semi-truck has been detained by police for an impaired driving investigation.

On Tuesday, police said that their officers responded to the rollover collision at approximately 8:05 p.m. Preliminary findings indicate the truck was originally travelling westbound when it veered into the center median, crossed into oncoming eastbound traffic, and rolled over.

Police are asking anyone who witnessed the incident, observed the semi-truck’s driving behaviour prior to the collision, or has dashcam footage to contact the department them at 604-859-5225.
