Surge Brakes: Federal Ruling
March 6, 2007

This information is provided by ABC Equipment Rental as an "unofficial summary" of the ruling made by the FMCSA. The actual official document is some 35 pages long. It can be downloaded and read verbatim from the Federal Register Online http://www.fmcsa.dot.gov/rules-regulations/administration/rulemakings/final/E7-3815-Surge-Brake-Final-Rule-3-6-07.htm the document number is: fr06mr07-10. This summary is our interpretation of the ruling.

For Surge brake equipped trailers with a manufacturers rating of 12,000 lb GVWR or less, the maximum trailer to vehicle ratio allowed is (1:75 to 1). Example, if a vehicle has a manufacturers GVWR (Gross Vehicle Weight Rating) of 6,000 lbs, you can legally tow a trailer with a GVWR of 10,500 lbs or smaller (6,000 x 1.75 = 10,500). If you want to know what size vehicle you will need to pull a trailer, just reverse the formula. Take the GVWR of the trailer, 10,500 lbs and divide it by 1.75 = 6,000. So you would need a vehicle with a GVWR of 6,000 lbs or better. We can only advise you of the rules; the liability of meeting traffic safety requirements always rests with the driver of the vehicle. If you are not comfortable towing a trailer, we always have delivery available with reasonable rates.
