What is the legal height for speed humps? Or where to find out?

Does it differ from place to place? I’m in a caravan park atm and the husband of the manager (who thinks he’s the boss) has put more speed humps in himself and even though we have a 4wd…it’s still awkward to get over.

    Speed humps on public roads are designed and built to Australian standards. The plans go through the local Council and the transport authority (in NSW, the RTA). Different types of speed humps are built for different purposes/environments and thus heights vary. If the humps are those small rubber or steel speed humps, generally with yellow and black coloured pattern, they are designed and built to standards and the heights should be okay.

    If it’s on a public street/lane (i.e can be located on street directory) and you believe they’re too high, contact the local Council. If it wasn’t approved by the Council (i.e. manager installed themselves) then they will face massive fines and charges.

    However, if the humps you’re talking about are built inside the caravan park and on private property, the owners have the right to install whatever they deem necessary. But as a caravan park and place of business, customers always comes first and complaints/suggestions can go a long way. They are obviously installed to prevent people speeding in place of high foot traffic, but they should have signs indicating the speed humps and a suggested speed or a speed limit on their property. If you believe the humps are too high, try driving over the humps at the suggested speed or just under the speed limit. If at that speed the impact is too great and can possibly cause damage to a standard (non-4wd) vehicle, they ARE liable for damages due to incorrect sign posting or installation of traffic devices. Similarly, if the humps are too high and someone on a bicycle goes over it and breaks their neck, that’s one large lawsuit, being a caravan park there’s plenty of riders with no helmet. Mentioning these to this guy (tool) who thinks he’s the boss should make you feel better.

    Hey Katfood,

    I’m with you on this one. I have had several back surgeries and speed bumps kill me. Strangely enough they have three in the circle pick up drive at the hospital, go figure. At my high school they put some really high speed bumps in which cause some damage to lower cars. The students got mad and poured transmission fluid on them. You may not know this but when you put transmission fluid on as-fault speed bumps it eats them up. Of course I don’t know what kind he put in, but maybe this will help.

    I don’t think there is any legal specifications, because most of them are placed on private property, so the property owner can do most anything he wishes….

    A speed bump is a bump in a roadway with heights typically ranging between 3 and 4 inches (7.6 and 10 cm). The length of speed bumps are typically less than or near to 1 foot (30 cm)

  5. UCANTCME Says:

    Generally, speed humps are 12 to 14 feet (3.7 to 4.25 m) in length and span the width of the road. The height of humps ranges from 3 to 4 inches (7.5 to 10 cm).[1] The length and height of the speed humps determine the speed at which traffic will travel over the devices. Shorter lengths and greater heights slow cars most drastically. When placed in a series 350–550 feet (100–170 m) apart, humps will reduce 85 percentile speeds by 8–10 mph (13–15 km/h)..
