What's the standard response to NSL +30 on a motorway?
Not me and my Desmond
If stopped at the scene then the rozzer will normally tell you what speed he's reporting you for, and what's likely to happen. Some may tell you you've been done for 100+, but then actually put 97/98/99 on the ticket. If they do that you'll get the normal £100 + 3 points COFP through the post. If you're reported for 100+ then they'll issue a summons to appear before the magistrates - probably in a month or so's time.
If it's a speed camera then it's tricky - they don't have to tell you what speed you've been clocked at till you get to court. You'll get a NIP first to nominate the driver (within 14 days) . If you then get a COFP then chances are it'll be less than 100MPH. If it's 100+ then much more likely to be a summons to court. The summons must be issued within 6 months.
If you end up before the beak for 100 MPH+ the sentencing guidelines for driving in excess of 101 mph on a motorway or dual carriageway are that they should consider a period of disqualification from driving for a period of 7 – 56 days (in addition to the imposition of a fine, costs and victim impact surcharge) or to endorse with 6 points.
NIP = Notice of intended prosecution
COFP = Conditional offer of a fixed penalty (3 points + £100 fine if you plead guilty immediatley)
You = "the royal you"
The above also depends on other factors, such as how many points are already on your license, and the road conditions at the time. My money would be on a one month ban and a big fine - £1000 or so.
