"Stress can affect your concentration and losing focus for even one second puts you at a greater risk of having a collision."
The insurer's statistics also revealed older drivers were more likely to crash in car park buildings than young drivers - with 20 per cent of collisions being in car parks for drivers over the age of 60.
Eight per cent of car park collisions occurred for drivers under the age of 20.
This might be due to a difference in lifestyle, AMI claims technical specialist Chris Kiddey said.
"This may simply reflect changes in lifestyle where older drivers find they're spending proportionally more time in car parks than they used to," Mr Kiddey said.
Tips to avoid dents in your car in car park buildings:
• Drive slowly and carefully in car parks and be courteous to others.
• When reversing in or out of a car space, drive slowly and don't just rely on your mirrors - look over your shoulder as well.
• If you can, reverse into a car space, so it's easier to see in both directions when pulling out.
• Do your bit by returning shopping trolleys to their bay.
• Use indicators every time you make a turn.
• Be patient and give others time and room to move.
• If you hit a parked car, do the right thing and leave a note with your details.
• If you witness a collision, pass on any information you have to the parties involved.
