Regular brake testing is standard practice for most and shows commitment to running a compliant fleet. DVSA Enforcement Policy Manager Dave Wood explains what you can do to make sure your vehicle’s brakes are up to scratch.
“Brake performance testing should be a key part of your maintenance regime that needs to happen at every safety inspection. And, if you find any braking performance problems while the vehicle or trailer is in use, you’ll need to get a measured brake efficiency test before you use the vehicle again.
“For most, this is standard practice and shows that you’re committed to running your fleet compliantly and protecting other road users.”
“But unfortunately some licence holders don’t meet the minimum standards and the consequences can be devastating.
“In 2015, DVSA examiners investigated a road traffic incident involving a 32-tonne tipper vehicle. Four people were killed when the vehicle’s brakes failed on a steep hill. Our investigation found the operator’s brake testing was far below the required standards. The company’s approach to brake testing was nowhere near thorough enough, and on five out of 13 safety inspection records, the brake test section had been left blank. In the other records, the comments were too limited for anyone to understand what they meant.”
Successful court convictions
“Two individuals from the company were each convicted of four counts of manslaughter at Bristol Crown Court. The company director was sentenced to seven years and six months in prison and the mechanic was sentenced to five years and three months in prison.
“The Traffic Commissioner revoked the company’s operator’s licence and both the company and its director were disqualified from holding or obtaining another operator’s licence for two years.
“Even if nothing this catastrophic happens, our vehicle examiners will still take your vehicle off the road and can issue you with a fixed penalty if they find dangerous problems with your brakes. This could lead to an investigation and referral to the Traffic Commissioner.”
Following best practice
“You should carry out routine safety inspections of your vehicles on a regular basis. A braking test needs to form a part of each safety inspection. If possible, you should always brake test a vehicle or trailer laden in order to get meaningful results. If this test shows the brakes aren’t working properly, then the vehicle or trailer isn’t roadworthy. You should also use a calibrated roller brake tester (RBT) to measure individual brake performance and overall braking efficiency.
“You could also use an approved and calibrated decelerometer to measure overall brake efficiency if you’re testing vehicles without trailers. And you should always try and obtain a printout of the brake test from either the RBT or decelerometer and make sure it’s attached to the safety inspection record. If you can’t get a printout, the inspector should record the results on the safety inspection report instead.
“If you can’t carry out a brake test during a safety inspection, the vehicle’s braking performance must be assessed using a road test. This needs to be carried out under controlled and safe conditions. The safety inspection record should also say that the brake performance was assessed by a road test.
You can use an Electronic Braking Performance Monitoring System (EBPMS) to assess trailer braking performance, using data collected while the vehicle is in use.
