“And don't forget 6 points within the first two years of passing the test means a ban and retest.”
It’s a point of pedantry, possibly, but that is not strictly correct, hc.
A “New Driver” (that is one who has passed his/her test for the first time less than two years ago) accumulating six or more points is not disqualified from driving. What happens is that the DVLA, when they are informed of the points, revoke the driver’s licence by writing to him and giving him five days' notice of the revocation. Until they receive notice of the revocation the driver can drive normally (though it should be noted that a driver expecting revocation will commit an offence if he drives normally believing the notice of revocation to have been "lost in the post").
After the licence has been revoked they can immediately apply for a new provisional licence and drive under the terms of that licence (‘L’ Plates, accompanying qualified driver, etc.) as soon as it is received. Many new drivers effected by this spend virtually no time off the road at all and I know of one who successfully passed his test (both parts) within about six weeks of his licence being revoked. The sanction (licence revocation) can only be imposed once. The “probationary period” of two years is automatically ended when a second test is passed.
