Roadcraft, the Police bible has an acronym (sorry if this is teaching granny to suck eggs): IPSGA I - Information P - Position S - Speed G - Gear A - Accelerate So, as soon as you see the "Information" in the road sign, that's then the time to plan a safe change to your position. Information has sub layers: Take, Use, Give. Take information in such as the road sign, traffic, what's behind you etc. etc. Use that information to plan what you do next. Give information out - such as indicators to give other road users information that you're wishing to change lanes. Go back to Information....... Information - Take (mirrors/shoulder check) - is there a suitable gap? Information - Use - yes there's a gap Information - Give - yes, my indicator is still on. Position - plan to move across Speed - does it need to change? Gear - if speed needs to change then do I need a different gear? Acceleration - or possibly deceleration - to safely change lanes. Information - all OK for a safe and considerate lane change? Yes? Position - change lanes Speed - is it still appropriate - the earlier Information will have allowed you to assess the speed and flow of the traffic in the lane you're moving into and adjust yours accordingly. Gear - is it still appropriate Acceleration - needed? Or not? Information - what's new? More signs, changes to the traffic flow etc. etc. and so on........ This, obviously, takes massively longer to type and read than to do but I'm sure you get the idea. The earlier you get the information the more time you have to plan and the better and less stressful your journey will be. So, after all that, I'd be looking to change lanes as soon as safely possible after I'd seen the sign. After all, everyone has seen the sign, so their use of Information would be something like.... There's a slip road coming up, so I need to be awake and alert to the possibility of other vehicles wishing to change lanes. Maybe it would be safe and sensible to create a bigger gap as I can see vehicles in that lane who might wish to change? Or maybe I can see a vehicle charging down Lane 3 with their left hand indicator on so perhaps they wish to use the slip road. Do I need to change speed to allow them a safer exit? Etc. Etc.

So where does the slip lane start? At the 1 mile marker and sign showing lane 1 veers off or where the shorter white lines are? macafee2 |

You have countdown markers for the Slip Road Marked with 3,2,and one 1 stripes. The slip road begins after the "1" marker. You use the markers to adjust your speed and position on the approach to the "Slip Road.

As for Lane Markings these help:
https://www.gov.uk/guidance/the-high.../road-markings Picking up on "Information" (and this applies at all roads) you'll mostly see "Lane Dividers" the short line followed by a large gap. If this changes then that's Information to used. There are, of course, technical standards about the width of the line, its length, the distance between them etc. So, if the lane divider becomes a "Hazard Warning Line" (the opposite of a lane divider, long line, short gap) then there's a hazard of some sort up ahead. That hazard, in this case, is the slip road. I'd want to be in the correct Lane as soon as possible after the hazard line starts and earlier if there's other Information to help out with Position. I use a different plan of action to Number 6. ".....You use the markers to adjust your speed and position (my highlighting) on the approach to the "Slip Road....." I'd rather have about a minute to get into position (From the information - the Road Sign) than using the 3, 2, 1, exit markers which at 70mph gives just 9 seconds to get into position. Obviously you make your own choices and create your own plan. Think of all those Police Camera Action shows where we see someone in Lane 3 diving across to try and make an exit. If I've misinterpreted then apologies in advance. For fun, have a look at the lines on some roads you know and see what changes and when it changes, particularly where there are bends, dips, crests etc. And one tip..... Generally the more markings on the approach to a hazard, the greater the danger. Last edited by AndyN01; 7th October 2021 at 07:47.. |

i did a driver awareness course, not because i'd been naughty but i NAUGHTY WORD-NAUGHTY WORD-NAUGHTY WORD- the chance to pay and do one, they too mentioned "the more markings on the approach to a hazard, the greater the danger". To me that was a new way of thinking and it stuck with me. Tried the link but nothing about slip lane markings, those short white lines. Cant find anything from my search at the internet macafee2 |

AFAIK Lane Markings are universal for all roads. But you've raised a good point that the lines on a normal slip road go from solid white between the hard shoulder (if there is one - whole different discussion ) and Lane 1 to the short line, short gap of the slip road. I need to do a bit more digging. |

Just reread your original post.... lane 1 becomes the slip road at the point that the lane dividers change, usually getting thicker and closer together. When coming off the motorway where lane 1 does become the slip road, I've come across this on the M6 & A38 locally Example of the road marking changing 1/2 mile from Junction 4A M5

if I read the OP correctly the question was When does Lane one become the slip road... Lane one does not become a "Slip Road" lane one stays as lane one and the "Slip Road" starts at the END of the count down markers.
