Many drivers believe that a lack of police on the roads is ensuring law-breakers increasingly get away with their crimes.
The RAC Report on Motoring shows that two in five (40%) drivers think it's unlikely that other motorists committing common offences - such as tailgating, texting at the wheel or undertaking - will be caught.
In fact, more than half of those drivers polled (51%) think it's improbable that someone texting while stuck in traffic will ever be caught.
Just 18% reckon such drivers are likely to be taken to task with the rest (22%) uncertain as to whether they will or won't.
Meanwhile, only 24% of drivers think others who tailgate will be picked up by police traffic officers, the report shows.
RAC technical director David Bizley said: "Our research shows that millions of law-abiding motorists are frustrated with the reduction of traffic police and believe that the chances of drivers being pulled up for breaking the law are now minimal.
"Motorists are tired of constantly seeing other drivers breaking the law and getting away with it so it is hardly surprising that they want to see a greater police presence on our roads to enforce motoring legislation more effectively, which would also act as a genuine deterrent."
