Almost 30 percent of drivers and passengers who died in traffic collisions last year weren't wearing a seat belt.
New figures from the Road Safety Authority found nearly a fifth of motorists don't always wear the belt when in the back seat.
An Garda Siochana has urged everyone to belt up, saying staff are continuing to witness 'devastating' scenes after crashes.
A driver risks three penalty points and a fine of 60 euro if they're found without the belt, while passengers over 17 can also be fined.
