speed bumps

warder6161

just went over a speed bump not travelling too fast but took a pipe/connection off because the under carriage bumped off the ground..i think it was caused because of the height of the speed bump anyone know what regulations/height and width these should be..and do i have any comeback on the damage caused to the car..:mad:

It's probably regulated but they'll probably blame your speed and maybe your car is lowered etc.
I still haven't met a bump I couldn't traverse going slowly.

I've come to an awful lot of speedbumps that take me the guts of ten seconds to get over simply because my car is sitting so low. No comeback on if you scrape on them though...I have to do literally 1mph over them and I still scrape my bumper or knock my sump or trailing arm off them

I recall a discussion before about ramps and there were no regulations which explaied why there were so many variants on them.
The thing that I dislike most is that they are usually put in 50km/h zones but you need to drive much slower to go over them. Are they saying that their 50km/h limit is not safe?

There are three bumps from my house down to the shops, the first and last are smooth and I don't have to slow down much to drive across whereas the middle one is the same height but more "square". For this one I must come almost to a full stop first. They're all on the same street.

There is some discussion regarding regulation here and a 2002 article here.

Noel Hamilton (61) told his counsel Gabriel Gavigan that he struck his head off the roof of his car when he drove over an unmarked ramp on Avonbeg Road, Tallaght, in October 1998. Mr Gleeson said the offending ramp had since been removed, but he examined similar ramps constructed on the same road by the same contractor.

He had found they ranged in height from 133mm to 144 mm, well over the 100 mm restriction set out in the regulations.

Following the case Mr Gleeson said that apart from excessive height, the Regulations were also often breached with regard to the positioning of ramps on or close to road junctions and bends, and on bus routes.

Mind, these are from several years ago.

Speed humps/bumps/ramps should be properly engineered to allow you to safely traverse them at the applicable speed limit. Not this current business of having to slow down to next to nothing to get over, and then speeding up again till you reach the next one.

Hi time for the roads authorities to get their act together me thinks.

then speeding up again till you reach the next one.

And they want us to cut down on Co2 emissions? Ramps only contribute to Co2 emissions as indicated above.

That would only work if all cars were roughly the same. As things stand, the same ramps which bring some of you to a standstill can be flown over at 50km/h in many French cars. Soften the ramps to the point where a slammed Honda can do, say, 30km/h and some other cars will be able to do 80km/h on the same stretch.

They want to stop speeding first, I assume.

they don't do that though, people still drive at speed in-between them, maybe even faster than otherwise to compensate for having to slow down for them in the first place

+1. Depends how soft the suspension is.

There's a misconception that hard=better handling so may cars have overly hard suspension, low profile wheels. Very little travel on the suspension. Completely unsuited to Irish potholes and ramps.

Well its slowing people in this thread down.

no warning before the bend..i was slowing down because of the bend also it was into a residential area..doing no more than 25km..just went down again and you would really have to go over the ramps at 10km or lower to be sure you will escape damage free !
