After a busy long weekend, the Haliburton Highlands OPP is reminding you to be safe.

Officers received 100 service calls, and many of the events involved cars, ATVs and boats.

Constable Tim Negus says speeding, liquor and lack of safety equipment was a factor in most of the events.

Negus says reducing your speed, wearing safety equipment and driving sober can reduce the risk of a tragedy.
