Millions of Britons are driving cars while high on illegal drugs, a report has said.
Some 2.8 million people have driven while under the influence of drugs, with four in 10 of these doing so within the past 12 months, a survey showed.
But one in three drug drivers still thought they were "very safe" or "quite safe" with just one in five admitting they were a danger on the road.
The poll of more than 2,000 people showed one in 10 drug drivers thought they would get away with it.
One in 20 admitted breaking the speed limit while high on drugs, with the same proportion admitting being involved in accidents.
The survey, carried out by Opinium for Direct Line car insurance, found 7% of the UK's 49.1 million adults admitted to driving having taken drugs. Of these, 41% - 1.1 million people - have done so in the past year.
In the last 12 months, one in three drug drivers had used cannabis, one in seven had taken cocaine and one in 10 ecstasy before taking to the roads.
Andy Goldby, director of motor underwriting at Direct Line, said: "Drug driving is as irresponsible as drink driving. The dangers of drug drivers on our roads are becoming increasingly apparent, with thousands admitting they have been involved in an accident while high or stoned.
"The effects of drugs can often leave people feeling overly confident or extremely relaxed, both of which are known to lead to dangerous driving behaviours. We strongly support the Department for Transport's (DfT) decision to clamp down on drug driving and would welcome further investment in effective roadside drug tests to screen drivers the police suspect are under the influence of illegal or strong prescription drugs."
Opinium Research carried out an online poll of 2,030 UK adults aged 18 or over on behalf of Direct Line on May 4-6.
