Can I use GPS unit instead of the car’s speedometer?

By grdem - 7 November 2011 57

Hello, just throwing this out here if anyone knows the answer:

I’m on ACT L’s at the moment and about to take the driving test in a few months. The problem is that my automatic car’s speedometer is busted and too expensive to replace – have to get the part from overseas. The car used to belong to my partner, and he taught me to judge the speed by using the tachometer and listening to the engine.

I’d rather not hire/borrow an unfamiliar car for the driving test, so my question is: can I take the driving test in my car, if I install one of those little GPS units that show the speed as well? Or in fact, can I take the driving test with my smartphone mounted on the dashboard with a speedometer app?

Thanks in advance if anyone can help with this!

What’s Your opinion?

You have a few months to go until your driving test:

Option 1: Get the car fixed.
Option 2: Borrow someone else’s and use the time you have to become familiar with it.
Option 3: Deal with it.

no sorry… Legally you need a speedometer in the car for it to be considered roadworthy and the GPS system does not replace one.

I guess it depends if the examiner decides that your car is roadworthy or not, but he’s not going to be able to ascertain that until you actually start moving…

If you’d wanted to take advantage of the situation, your best bet would have be to start the test, and quickly say..” Hey, my speedo has just broken. ” Give the examiner some time to digest this and then offer to complete the test with your phone as a speedo.

I’d rather try that then give someone the option of cancelling a test because you’ve admitted that your car isn’t fully functional.

Thanks for your suggestions everyone. We’d originally intended to hire/borrow a car for the driving test anyway as we’d meant to sell this car months ago (but that got delayed). I’m just really comfortable with this car and would like to use it if possible (it’s an old but zippy little sports hatchback that drives really well).

Regardless of accuracy, the GPS is not going to give you instantaneous speed.

Just use it, if you can judge your speed without it, just “neglect” to inform the instructor that it doesn’t work, maybe he’ll be impressed with your… speed judging skills.

Think about it. What if it’s cloudy?

Driving an unroadworthy car is an instant fail – you won’t even get out of the carpark.

If at the time of going for your provisional license, you can’t adapt to driving a different car and are therefore worried you’ll fail the test in a borrowed/hired car (especially an automatic), then you are not ready to hold a license. Simple as that.

This thought also crossed my mind.

Does not having a speedo make the car unroadworthy? It’s not like you absolutely need one in order to be able to operate the car safely?

If you consider that driving within the speed limit is an aspect of operating the car safely, then yes, it does.

I’ve never yet found someone who can accurately estimate their speed under 40kph, which is the speed of some roadworks. Thus, not being able to tell your speed in a 10kph shared zone makes most people unsafe.
Realistically, it’s common sense, which isn’t common because people feel the need to question it.
Cars have to meet certain guidelines to be allowed onto public roads. A speedometer is one of them.

People are just hopeless at figuring what speed they’re driving at with any level of accuracy unless they have one.

This has to be a gee-up.
