The fine for a driver or passenger not having a seat belt properly fastened is $353 and three demerit points, but drivers can also be fined for each individual person travelling in their car without a seatbelt.
Last year, 705 motoristswere issued a traffic infringement notice or formal caution for driving without a seatbelt or having a passenger not secured by a seatbelt.
"While most Canberrans buckle up, some continue to drive improperly restrained, with passengers not wearing seatbelts or with children on board not wearing seatbelts," ACT Police traffic operations Sergeant Rod Anderson said.
"Whether you're a parent dropping the kids to school or a tradie just ducking down to the shops with some mates, it is an offence to permit passengers of any age to travel in your car without seatbelts."
During 2013, 19 drivers were issued infringement notices for having children under 16 in their car unrestrained or improperly restrained.
So far this year, 11 drivers have been issued infringement notices for the same offences.
"Seatbelts are a proven safety feature and there's no excuse for not wearing one," Sergeant Anderson said.
"A properly adjusted seatbelt or child restraint greatly reduces the chances of being killed or seriously injured in a collision."
