The PSNI has urged road users to take extra care over the long Easter weekend.
Nine people have lost their lives on Northern Ireland's road so far this year.
According to PSNI statistics, the most common reasons for serious road crashes is driver inattention, followed by speeding with alcohol or drugs in third.
Chief Inspector Diane Pennington said their statistics also indicate there is an increased risk of road crashes during holidays.
"It is critically important that everyone focuses on road safety, as our statistics indicate that there is an increased risk of collisions during public holidays," she said.
"In the coming days we will be paying particular attention to our road network and will be liaising closely with our An Garda Siochana Traffic Corps colleagues in the border counties, specifically looking for road users taking unnecessary and potentially life-changing risks."
