MORE than half of Queensland motorists were willing to break the law to alert others to speed traps, according to RACQ.
Research found almost 55 percent of motorists flashed their headlights on a regular basis to warn other drivers about speed cameras in the area, an increase of ten percent on the same time last year.
RACQ Executive Manager Insurance Communications Mike Sopinski said motorists should be aware the practice was illegal.
"Many motorists may not realise flashing the high beam at approaching traffic is an offence and is dangerous," Mr Sopinski said.
"You may think you're doing a good deed or even a community service by alerting others to an upcoming speed camera, but flashing your headlights can actually be quite dangerous.
"A momentary loss of concentration can have deadly consequences - especially when cars are being driven at highway speeds."
RACQ research found the most common methods for locating speed camera sites:
1) Radio reports of locations - 31.7 percent
2) Tip offs from family and friends - 19.2 percent
3) Social media sites - 12.8 percent
4) Mobile apps - 8.0 percent
5) Radar-detecting devices - 7.4 percent.
Mr Sopinski said the simplest way for motorists to avoid being caught by speed cameras or police was to not speed.
