Sussex Police is warning drivers to beware of black ice.
Between midnight and 7.45am today (Monday January 28) there have been more than 40 crashes on the county’s roads.
More than 30 of these have involved single vehicles sliding off the road due to ice.
So far none of the incidents is reported to have caused serious injury, however, a Sussex Police spokesman said; “Rush hour drivers are urged to take it easy on the roads, especially outside towns. The ice cannot readily be spotted, so please slow down and allow extra time for your journey.”
