Law Or Not??

1. ## Law Or Not??

Greetings,

So far this place has been great filling me in with little details.

One quick one for those who know for sure. I found this in the riders book:

Is this speed the law or is it just suggested? It kind of says both.

2.

3. it is suggested:

a sign with a yellow background is only information or recommendations

a sign with a white background is the law

a sign with orange background is for construction or temporary changes and can be law or just info.

yep... dat;s all in da book.... FYI normal theorem that applies for sportbike riders is to take recommended corner speed and double it.

5. Convert it to imperial, round to the highest prime number then double it.

Math nerds ahoy!

6. I treat all the signs as suggestions - that way you don't have to bother remembering the difference.

7. ## CAUTION--- Watch out for the Blue signs

......

8. a friiends brother is an engineer who reconstructs collisions for legal purposes. According to him, the suggested speed in a corner is based on how fast you can safely take the turn without losing traction with a coefficient of friction close to that of a car on ice. I don't remember my physics or what the number is.... but apparently thats how they come up with it.

9. I've heard that too but they test it by driving with a level in their front dash and the recommended speed is the speed in which bubble does not move.

apologies... I neglected to include the switch to imperial units back to motorcycle math school for me!

Double it and add 40 is the rule of thumb.

12. The funny thing is, turns that say recommended 30km/h are all different, aka one taking winston st to goverment road, I can do that one 90 in the rain, while up towards cypress, the hairpin by the lookout is much sharper of a turn.

If that cypress one is 20, then my bad for the example, but there's plenty sharp 30km ones out there.

13. Yellow ones can be taken at face value only on the rear wheel....

14. From car driver's point of view I don't think these numbers are calculated properly or they use any physics for it. Even the numbers mentioned on hwy 1 (coastal) in California is just a guess work. There are turns with 15mph sign and you can easily drive 40mph on them and there are some tight turns with 30mph sign but was difficult to drive at 30-40mph on them.
I just use my judgment (look through the turn) and ignore the suggested speed sign.
Maybe the road construction guide book has correct procedure for calculation but not all people work by the book.

15. I did a long one a couple yrs ago at about 1350 kms in a day and one thing I noticed is in the US when they say slow to 50 (and yes its easy to forget MPH) its a suggestion, when they say slow to 40 you best pay attention and when they say slow to 30 you better slow to 30 or your in frigging trouble... thats for sure! So in a nutshell the higher #'s don't matter so much but once they start saying 20 or 30 you better pay attention and I mean NOW...

16. I stopped looking at corner speed signs a while ago, and take corners at a speed which reflects how far through the corner I can see.
