Steering lock ADR

[Jethrow]

OK, this is not meant to be a pissing match, but an immobiliser is not the compliance means for 5.1.1. In fact, you are reading the rules out of context. That section actually means that you must not be able to start the car, AND must not be able to steer or move the car forwards, until the protective device, whatever it is, has been put out of action.

So, for most cars, once the steering lock (protective device) is put out of action via turning the key to that first click, then, and only then, are you able to start the car, AND then move it or steer it.

The one protective device has to prevent both 5.1.1 and 5.1.2 from occurring.

And again, typically, it is a steering lock that does that.

The immobiliser is a separate thing. And, again, largely, it is something that might also meet the intent of this regulation. Tho I agree it does not specifically meet requirements because it does not act in the manner called out in the reg. Probably because this is technology that came about after the reg was written.

Anyway, this is a tricky issue for me because the kit I am building does not have a steering lock. So I am a bit stumped on this too.
