Accelerating from a marked 30mph limit to a 60mph limit.

[maxp]

Hi guys, I know this is basic, but I just wanted to clarify as I couldnt find any mention of it in the highway code and wanted a bit of confirmation!

So, if im riding in a 30mph zone, and I can see there is a national speed limit sign 20 metres ahead, I take it I must wait until i am level with the new speed limit sign before I can accelerate from 30mph? (The 30 -> national sign is just an example)

I heard someone mention that they should be doing the increased speed by the time they reach the increased speed limit sign, which is what got me confused!

short answer is yes.

if you're in a 30 zone you 'should' only do a maximum of 30.. no ifs no buts.

so if the speed limit changes to a higher one you 'should' accelerate only when you are in said limit change

Don't listen to the the person that told you otherwise. The limit begins at the sign, not before.

Now, it you are talking about REDUCING speed then, yes, you should be at the lower speed when you get to the sign, not after.

Never did the lifesaver but did mirror checks when changing speeds on my Mod2 and didn't get any minors in that area

As others have said... wait until you're level with the sign and then increase your speed. In reality most people speed up before... but on your test wait until you're level with the sign.

- get level with new limit sign
- quick mirror check
- increase speed

On the point about mirrors/lifesavers, I would say it's especially important to do the mirror checks and possibly lifesavers when coming down to a lower speed. That's when the idiot behind you talking on the mobile may go through or around you at speed.

There's an off ramp near me that has a 30 sign half way through and absolutely no one, not even grandmas on the way to church on Sunday, do any less than 60mph at that point. My instructor said the examiners sometimes take people down there on the mod 2 and if there's some bored looking white van man a foot behind your tail, don't try to do 30. Screw the test; don't die.

OK, this is what the DSA want. This is how instructors should teach it.

Changing speed you carry out a MIRROR check only.
Changing your position from centre of lane MIRROR and LIFESAVER.

It is a waste of time doing a lifesaver if you are not moving left or right. The point of a lifesaver is to check your blind spot before you move into it.

Why would you check a blind spot when accelerating or slowing down? You are not moving across into it, you are carrying on down the centre of your lane, therefore a waste of time!

Instructors have started to teach pointless, time wasting checks to students, you want to be looking forward, not behind you. I've taken students to test, taught by other instructors, who do a lifesaver before moving off at a green light - pointless.

You will not pick up even a minor for changing speed without a lifesaver because that is how it should be taught.

A girl I know got caught doing 40ish on the run up from a 30 zone to a 60.

Plod had a hand help speed camera and was waiting to catch people on that stretch!
