Tester drives car, looks at speedometer for when to use decel (20mph) and sees the speedo not working. Should he continue to test the brakes using a decel with a none working speedo and guess the speed or head back to garage and abandon the test with a fail for none working speedo attached?

What do you think? Is that "clearly inoperative", iyho?

We had a old car where the speedometer or odometer weren't working.
Could tell the speed based on the rev's - was easy and could still do it in my current car
Passed one MOT ok but had to get it fixed for the second as obviously the odometer would show no miles since the last test.

And the car was eventually scrapped so we didn't sell it on with incorrect miles

Not an MOT issue at all. You don't even need to have an odometer fitted for the MOT - and, even if it is, the reading is only noted on the certificate for information.

I had a car with four consecutive MOTs with the same mileage, followed by one with a mileage 50k lower (I changed the speedo). No problem whatsoever.

And the car was eventually scrapped so we didn't sell it on with incorrect miles

It's perfectly legal to sell a car with a mileage you know or believe to be wrong. What's illegal is claiming it's right, in order to get more money.

I know what to do, I'm seeing if you do

Do you continue to test the brakes or not?

Which of the grounds for abandoning a part-completed test are you hinting it might come under?

Danger of injury or damage? Please!

An interesting point. Emergency stopping is inversely square to the speed.... So if the tester achieves the 'minimums' prescribed by the testers manual, would it matter? Of course you now have the broken speedo to fail it on,

Or perhaps a broken speedo is just a fail per se?

why would you not carry on what would be so dangerous for you to abort the test.

If an mot tester has to carry out a decelerometer test and notices the car speedo isn't working, what do you think he should do?

Fail test, RFR 3.7.1 "Brake performance test unable to be carried out".

The decelerometer test requires the tester to drive at a speed of "approximately 20mph" which requires a speedo to judge. No speedo = unable to carry out test according to manual.

Note to certain posters, this is an entirely different matter to drivers judging "safe speed" without a speedo, because for the brake test a specific figure is given rather than "at a safe speed for testing".
