i think you get fined for it... depends on the city you live - you get charged abt £80 - £120 i think. If the officer was kind enough, he may let you go with a warning..
I hav recently passed my driving test with bill plant.. my instructor was excellent.. i got only 3 minors (believe it!). my instructor number is 07885785334 and ask for Parazh. I bet you will pass first time with him.. Good luck mate
