A survey of 3,000 by the IAM into smoking and driving laws reveals 56% in favour of a ban
3/4 of the respondents thought that lighting a cigarette whilst driving was the single most dangerous aspect of smoking whilst driving while 46% thought it was as dangerous as using a mobile phone whilst driving.
It is unclear how a ban would be enforceable; in the same way driving whilst using a mobile phone is an offence but still motorists use their phones whilst driving. 45% thought a ban wouldn’t be enforceable.
