sounds like the "officer" has taken the broken down car as a trailer and as it weighs more than 750kgs issued a ticket for driving outside his licence.

having driven for many years in both cars and HGV's i've come accross many "officers " that don't know the law. i agree with tony ludford find a motoring solicitor and contest it.

many "officers" issue fixed penalty notices knowing most will not be contested so get away with their mistakes and everyone is non the wiser!!
