I recently got done for speeding along wanneroo road where a stretch of it drops from the normal 70 down to 60 (which I didn't know... thought all of wanneroo road was 70!).

I got pinged by a cop with a handheld laser doing 82km/h, and he only allowed a 2km margin of error bringing it down to 80km/h shafting me with a $300 fine and 3 demerit points. I know that multanovas must allow for a 3km margin of error, but the cop was being uncooperative and obviously wanted to get his quota up and put me in the 20-29km bracket rather than the 10-19km/h bracket which would have been less money and points.

Now my question is what is the margin of error police have to allow for HANDHELD speeding cameras? I've been searching on the net but can only find the margin for multanovas. A link to the source would be helpful.

I have no problems with paying a speeding fine if I get caught, but I do have a problem when I think the cop is breaking the law to penalize me more.

yeh and 2+2 = 6.3

I thought it was 2+2 = 100

Darn... looks like I need to retake my math class again :D

& which section of wanneroo is this on?

I know that the section where I travel alot on (the section near along dogswamp) there is a slight hill going up & they like to put their speed cams there. Was working along that road once & notice tons of cars getting flashed >_>"

im pretty sure its 2km error as lasers are more accurate then mutinovas. shoulda said it was the car infront/behind, i got away from that excuse before which was darn lucky on wanneroo aswell just after morley dr. intersection. did 40km+ on tonkin hw and had 7 points taken off with 1k fine. since then ive bought myself a radar detector. they work good but only if your doing less than 90kms in order to stop in time.

Gazza is right with the 10% speedo calibration... they only have to make their speedos accurate within a 10% margin. You never know, you might have a speedo that is dead on but with 10% margin for error up their sleeve it's doubtfull.

The lasers and multanovas do not have any margin of error. Each unit (in a perfect world) is tested with a tuning fork and calibrated. There will be actually variences due to the angle the laser is fired from (eg two lanes of traffic, cars side by side... car closer will be slightly different to the car further away)... the good thing there is that cops kow this and they will usually (as they have in this case) removed a little for angular margin of error. Unfortunately with multanova's, as they are a basically an automatic letter in the mail after a quick photo review, there isn't anyone who will down grade your speed.

What this means is that you could be thinking you are doing the right thing on the freeway, putting along at 100km/h on your speedo and then get flashed actuall doing 110km/h... on a long weekend thats going to cost you $150 and 4 points thanks very much Mr Car Manufacturer.

Flip side is you could be over on your speedo and actually under the speed limit... fingers crossed all of our speedos are this way inclined.

    • Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement
    • This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too  
    • hows it fellas, my first post here which seems crazy cos half the forums i read are like the same age as me haha. to make a long story short ive got an r34 sedan (rb25de neo auto) which im swapping to a s0/s1? rb25det, r33 big box and nismo gt pro lsd. i have the motor and gearbox all bolted up outside the car, old motor and trans out. i bought the motor with stock ecu and loom, do i switch over to that? or will it be easier to get a r34 manual ecu and keep the loom if thats even possible.  also engine mounts look different, anything else thats different or incompatible? cheers, hope this all makes sense Paddy

    • Plan on the day will be to park trackside. Depending on space availability we will try put a small shade tent and a few of the cars on top of the hill inside turn 3, this is an easy to get to parking area with views of Turn 2, Turn 3, Turn 4 and Turn 5 and limited other pieces of the view around the track. IMPORTANT NOTE! One consideration from previous years is from memory the trackside parking sells out before the admission tickets, for that reason I encourage anyone planning on coming to buy tickets for parking now via the official website; https://www.worldtimeattack.com/ The type of parking you are looking for is 2 Day Park & View (Access Around Venue) Vehicle Pass Only Please note this does not include admission to the event itself, remember to grab that also, and kids under 12 get in for free!
