Advanced Stop Line

I've received a letter from the Metropolitan Police regarding advanced stop lines. They've asked me to circulate it, so I'm putting a copy here. I assume that they sent it to me because I've previously reported some incidents to Roadsafe London. I'm surprised that they don't have a copy of this letter on their website or their Facebook page, so I'll understand if anyone is sceptical about this; there have been a few hoaxes going around which claim to come from the police. However, this looks legitimate to me, and it came from a suitable email address (


The Metropolitan Police Service is committed to reducing serious traffic collisions and the purpose of this letter is to increase driver and cyclist’s awareness and reduce road crime.

We have developed a web based information reporting system called 'Roadsafe London' to support us in this aim. Roadsafe London is accessible to the public via

Roadsafe is receiving a high number of complaints regarding Advanced Stop Lines (ASLs). Cyclists are complaining about vehicles encroaching into the reservoir when the signals are red this understandably makes them feel vulnerable.

If submitting footage regarding a complaint of this type please can I ask that the footage shows them driving over the ASL. Cycling up to a junction and seeing them in the box and filming them is of no use.



Some signal-controlled junctions have advanced stop lines to allow cycles to be positioned ahead of other traffic. Motorists, including motorcyclists, MUST stop at the first white line reached if the lights are amber or red and should avoid blocking the way or encroaching on the marked area at other times, e.g. if the junction ahead is blocked.

If your vehicle has proceeded over the first white line at the time that the signal goes red, you MUST stop at the second white line, even if your vehicle is in the marked area. Allow cyclists time and space to move off when the green signal shows.

Laws RTA 1988 sect 36 & TSRGD regs 10,36(1) & 43(2).

The ASL should have a lead-in cycle lane so that cyclists can legally gain access to the reservoir ahead of the motorists' stop line. Cyclists are not permitted to gain access through the solid white line, by entering the cycle box in this way they are also committing the offence of Contravening a Red Traffic Contrary to section 36(1) of the Road Traffic Act 1988, regulation 10 of the Traffic Signs Regulations and General Directions 2002 and Schedule 2 to the Road Traffic Offenders Act 1988.

Please could I ask that you circulate this message on your forums.

Yours Sincerely

This is mainly relevant to people who use video cameras to record examples of dodgy driving, but it's also useful to be aware of the relevant laws. Personally, I often use a helmet camera when I'm cycling. I recently bought a Contour +2, since my old ContourHD 1080p is having trouble with the power button: I have to open the back of the camera and poke it with something, a bit like using a paperclip to open a CD/DVD drive. The old camera is out of its warranty period (1 year), and the support section of the Contour website says: "We do not currently offer true repair services for any cameras out of warranty since it is often much less expensive for a user to replace a camera than it is to repair it." That's not amazingly useful, but hopefully I can find a camera shop that would be able to help me. If I can get that fixed then I'll use it as a rear-view camera. In the meantime, the new camera has the same form factor so it works with my existing helmet mount, which is useful. They've also merged the power and record controls, so the slider handles both: that's a much better design, because the slider is more robust than the button and I can operate it by touch with gloves on (i.e. when the camera is on top of my head).

For those who drive, you may find that a "dashcam" (dashboard camera) is useful; the Contour cameras have a flat surface mount for this, as do cameras from other manufacturers (e.g. the GoPro). Apparently this is quite common in Russia, and the Guardian have a compilation video. I don't know whether any UK insurance companies would offer a discount for this, but it may be worth enquiring.
