In the UK, green P plates can be used voluntarily by drivers that have just passed the driving test.
The ‘probationary’ plates or P plates as they are commonly referred to allow other vehicles on the road to acknowledge that a driver has only just passed the practical driving test and although technically they should be up to test standard, they should be provided with extra time and space in the course of driving to allow for any mistakes made.
1 in 5 new drivers according to the Insurance companies will be involved in an accident or 1 in 4 will be involved in a fatal accident. No this does not mean they caused them but due to lack of experience make a mistake in knowing how to avoid the accident
In certain countries, P plates or other types of plates are compulsory; however, in England, Scotland and Wales, no law or legal requirement are stating the compulsory use of P-plates. It is entirely the driver’s decision whether they wish to use them or not. At the moment.
If a driver does decide to use P plates, there is no law stating the duration in which the plates can be displayed. The driver can use them for as long as they wish and until they feel confident enough to remove them.
The only requirements for the use of green P plates in the UK are that a driver must have passed the UK practical driving test. They are not by law required to use them. There is no legal size requirement for the plate being displayed
P plates like L plates are used to inform vehicles that a driver has limited experience on the road and maybe prone to making mistakes. Driver’s reaction to P plates, however, is often quite different from those displaying L plates.
Although a driver displaying L plates will have slightly less experience than that of P plates, other vehicles know that there is likely an experienced driving instructor sitting next to them with dual controls that have ultimate control on any given situation. As a result, L plate learners often receive a pretty hard time off other vehicles impatiently trying to get past or hurry them along. Sometimes to such an extent, that many driving instructors often think it would be safer not to display L plates at all.
P plate holders often receive a much more lenient attitude towards them, however. As with L plate holders, they have very limited experience but are significantly more vulnerable as they are solely in charge of the vehicle. Other drivers know this and are therefore less likely to bully them due to the possibility of pushing them into making a mistake and potentially causing an accident.
So yes, displaying P plates is a good idea and should be displayed for as long as is necessary to become a confident driver.
P plate drivers are significantly more vulnerable than learner drivers as they have very little experience and are completely left to their own devices. Pushing a P plate driver to hurry is likely to stress them and increase the potential of an accident. Upon acknowledging a P plate driver, provide them with a greater following distance and more time to react at junctions and roundabouts.
