The police and local authorities enforce the UK Highway Code parking regulations. You must park your vehicle in the correct manner to avoid getting a ticket and a fine.
PARKING A VEHICLE AT THE ROADSIDE: We refer to the current UK
Highway Code roadside parking law.
It stipulates that unless it is 'absolutely' necessary, you should try to avoid making a stop on the highway as a chosen place to park your vehicle.
Instead, motorists should use 'specially' marked bays identified by white lines. Thus, you should use off-street parking areas wherever possible.
Follow these guidelines if you need to stop a car on the roadside during the day time. But, there are further restrictions for
parking a vehicle at night time.
