The common exemption for BB holders is on yellow lines (usually as long as there are no loading restrictions, ie yellow marks on the kerb)
The following is an excerpt from the BB parking rules:
The Blue Badge is not a licence to park anywhere. Like other road users, you must obey the rules of the road, as laid out in the Highway Code. Here is a list of places where you must not park.
Places where a ban on loading or unloading is in force, as indicated above by kerb markings. You may wish to check whether a
particular local authority has, exceptionally, chosen to allow Blue Badge holders to park where there are loading restrictions.
Parking places reserved for specific users such as resident’s bays or loading bays. You may wish to check whether a
particular local authority has chosen to exempt Blue Badge holders from these restrictions.
Pedestrian crossings (zebra, pelican, toucan and puffin crossings), including areas marked by zig-zag lines.
Clearways (no stopping).
A bus stop clearway during its hours of operation.
An urban clearway within its hours of operation. You may pick up or drop off passengers. All parking is forbidden.
School ‘keep clear’ markings during the hours shown on a yellow no-stopping plate.
Bus, tram or cycle lanes or cycle tracks. Badge holders are not entitled to drive in bus lanes during their hours of operation.
Where there are double white lines in the centre of the road, even if one of the lines is broken.
Suspended meter bays or when use of the meter is not allowed.
Where temporary parking restrictions are in force, as shown for example by no-waiting cones.
13. Safe and responsible parking
The Blue Badge is not a licence to park anywhere. If you park where it would cause an obstruction or danger to other road users you could be fined or receive a Penalty Charge Notice or have your vehicle removed.
Do not park where it would endanger, inconvenience or obstruct pedestrians or other road users. Examples of dangerous or obstructive parking include the following, although there are others:
- school entrances, bus stops, on a bend, or near the brow of a hill or hump bridge
- parking opposite or within 10 metres (32 feet) of a junction, except in an authorised parking space
- where it would make the road narrow, such as by a traffic island or roadworks
- where it would hold up traffic, such as in narrow stretches of road or blocking vehicle entrances
- where emergency vehicles stop or go in and out, such as hospital entrances
- where the kerb has been lowered or the road raised to help wheelchair users
- on a pavement, unless signs permit it
If you do not drive yourself, you should share the information in this guidance with the person who will be carrying you as a passenger.
You cannot legally be wheelclamped on the public highway (‘on-street’) for parking offences, provided you correctly display a valid Blue Badge according to the rules of the scheme.
Parking in forbidden areas or where it would endanger or obstruct other road users is an offence, which could result in you receiving a parking fine. You could also be prosecuted, have your car towed away and the badge withdrawn.
