It is now supplying all new vans across the whole of the UK with a sticker reinforcing a smoking ban in the vehicle.
Lex will supply the double sided window stickers and let fleet operators make their own decision as to whether they are fitted.
But bosses worry that the March deadline will not be met by Scottish fleets because of confusion about the process to report drivers who have been smoking in their vehicles. It predicts that firms will have to set up hotlines for people to report drivers smoking on the road, piling on administrative burdens.
Managing director Jon Walden said: ‘We have also had it confirmed that Scottish police will be checking vehicles to ensure they have a no smoking sticker inside the cabin.
‘They have said they will be taking the new legislation seriously and will be running spot checks to ensure drivers have been educated about the no smoking ban.’
