Braking performance assessment requirements from April 2025

Braking performance assessment requirements from April 2025

In a significant move to enhance road safety, the UK’s Driver and Vehicle Standards Agency (DVSA) has announced that, effective April 2025, there is an expectation that every safety inspection will include a brake performance assessment using either an RBT, a suitable electronic brake performance monitoring system (EBPMS) or a decelerometer with temperature readings. If EBPMS is not used it is expected there is a minimum of four laden brake tests spread evenly across the year, this can include the annual test.

Acceptable reasons for not carrying out a laden brake assessment.

Vehicles where laden brake assessments may not be possible or where additional loading would be difficult are listed below (this is not an exhaustive list), however there is an expectation that at least four of the assessments will use an RBT unless the construction or weight of the vehicle prevents its use.

  • Vehicles where under normal operating conditions (more than 70% of the time) run at less than 65% of the permitted axle weights. This may include car transporters where they are designed for that specific task
  • Furniture removal vehicles – Only when designed and constructed as a furniture removal vehicle
  • ADR – Only when the load is considered dangerous and specialist facilities are not available
  • Vehicles operating at 50% or more of permitted axle weights when unladen – This could include fixed plant, mobile libraries, compactor vehicles, exhibition type vehicles, bullion vehicles, etc.

Where a laden brake test is not carried out a risk assessment detailing the reasons, must be completed by a competent person who understands braking systems and its components at every safety inspection.

There must be an evaluation of the vehicle/ trailer performance report before every safety inspection by a competent person who can interpret the data. The evaluation must be signed, dated, and attached to the vehicle record together with the performance data report. The evaluation and data report may be a single document.

To allow flexibility vehicles can be presented for brake testing up to 14 days before the safety inspection date; this allows the operator to conduct a laden brake test during the vehicle/trailer normal activities without the need to specially load it.

Reliable brake testing is crucial to ensure road safety, helping to identify any potential brake issues that may lead to accidents on the road, minimising risks to the HGV drivers and other road users.

 

 

What does this update mean for you?

To follow best practice and comply with the proposed new legislation, the DVSA expect that with every safety inspection a brake performance assessment is completed with an RBT, suitable electronic brake performance monitoring system (EBPMS) or using a decelerometer and taking temperature readings as the sole method for evaluating brake performance.

In some cases, a loaded brake test may be impractical. As such, if a vehicle or trailer consistently operates under specific conditions, exemptions may apply. Examples include:

  • ADR vehicles: when the load is considered dangerous, and specialist facilities are unavailable.
  • Livestock carriers: when recreating the load is not possible.
  • Noxious load carriers: only if the vehicle is specifically designed for this purpose.
  • Furniture removal vehicles: only if the vehicle is specifically designed for this purpose.
  • Public service vehicles: this includes prisoner transfer vehicles.
  • Vehicles that operate at 50% or more of permitted axle weight when unladen. This could include fixed plant, mobile libraries, compactor vehicles or bullion transport vehicles.
  • Vehicles that more than 70% of the time run at less than 65% of the permitted axle weights, these may include car transporters or unladen tri-axle semi-trailers.

For businesses running vehicles not fitted with an EBPMS (currently only available on trailers) or exempt, a minimum of four laden RBT assessments are required, these are to be spread evenly across the year and include the existing requirement to conduct a RBT at each MOT test. To ensure minimal disruption, these tests can be completed as early as 14 days before the next safety inspection date.

A risk assessment (example here) must be available to support every safety inspection where a laden brake test is not completed. The operator will still be responsible for a risk assessment is in place to justify any exemption. This assessment should be:

  • Available to review during every safety inspection.
  • Updated annually, or whenever there is a change in vehicle use.
  • Retained with vehicle maintenance documents for 15 months.

 

What Should Our Customers Do?

At Mac’s Truck Rental, we are dedicated to providing safe and roadworthy vehicles to our customers and as part of this dedication we will be working with our customers to ensure they re-main compliant.

To achieve this, we will continue to complete our standard 4 laden RBTs per year across our managed fleets, while supporting our customers’ unique operational needs but will offer an increase in the frequency of the laden brake tests being conducted at the customer’s request. (Conditions apply).

We will be available to assist our customers, offering advice on how the new requirements affect their operations, any potential cost implications and providing information on keeping their own fleet in compliance.

Truck Maintenance

Fill in your details below to get more information from the team at Mac’s Truck Rental, whether you’re looking into contract hire or simply want to know more about one of our trucks.

Do you know how much you’re spending per year on your truck maintenance costs? Operating a commercial truck is incredibly expensive, but this is a necessary investment when working in the construction, waste and transportation industries.

The majority of modern trucks have systems in place that will notify you of any irregularities whilst driving. Everything from tyre pressures to oil warning lights are integrated into your trip computer, however, what can you do to spot these issues before they become a costly problem?

We wanted to share some of our top tips with you on how to reduce truck maintenance costs by creating a checklist, with tips on the steps you can take to decrease costs.

  • Enforce your daily walk around routine.

    • The Freight Transport Association (FTA) found that over 50% of the safety defects uncovered by its Vehicle Inspection Service could have been picked up by the driver, during their daily walk-around check.
    • By implementing a system of reporting and recording faults on a daily basis, you’re much more likely to spot issues before they become substantial problems, both legally and for the sake of the cost to your business.
    • The Government have a handy guide for daily walk round routines here
  • Change your oil regularly

    • Changing your oil is perhaps the simplest, but most effective way of prolonging the life of your vehicle. Due to the nature of commercial vehicles, you can spend a lot of time with the truck sat idling whilst waiting to load up or in heavy traffic.
    • This results in your oil breaking down quicker, and it not providing the efficiency it did when new. By changing your oil frequently, such as every 3000 miles, you ensure that your engine is well lubricated and the heat generated through friction is absorbed more effectively, improving longevity and performance.
  • Make sure your engine & coolants are topped up

    • The majority of businesses we work with spend time doing short journeys, often between the same locations day in, day out. During these short journeys, especially if you’re stopping and starting frequently, the oil can have difficulty building up enough pressure to protect the engine, which creates wear.
    •  Also, due to the nature of commercial trucks, they can heat up to incredibly high temperatures. Ensuring your coolant is topped up means more heat is distributed away from the engine, before returning to the radiator for cooling.
    • Often both of these will deplete over time due to the heat trucks generate, and it’s important to keep them topped up for efficiency and reliability.
  • Check your suspension

    • Over time, especially for commercial vehicles carrying a great deal of weight, suspension components can wear out. Although it sounds like common sense, you can usually spot if this is the case by experiencing a rougher ride than normal, and beginning to feel more bumps and shakes are you drive.
    • By checking your suspension regularly – through visual inspections, bounce tests and braking tests, you can identify is your suspension needs assessing.
    • This is particularly important for commercial vehicles as you have a health and safety requirement to the driver, plus if weight loads aren’t being properly absorbed whilst driving, they can become dangerous.
  • Inspect tyres for tread wear

    • Especially on larger trucks, rotating tyres is imperative to ensure they wear down at an even rate. When travelling long distances or carrying heavy loads, you may have to go outside of manufacturer’s recommendations in terms of tyre pressures, as they can’t always predict the weights you’ll be carrying.
    • Ensuring all of your tyres are balanced, and the tracking on your wheels is correct, you will further minimise tyre wear.
    • As a quick side note, looking at tyre wear and whether they’re wearing evenly can help out with our previous tip – indicating suspension could be failing on one side if the tread is lower.
  • Change your air filters

    • Your truck needs clean air to cool and function at the most efficient levels. Over time these can become clogged up and not perform as they did when new, but luckily it’s easy to maintain air filtration systems. Usually these can be taken out, washed and replaced, or replaced with an entirely new filter at a low cost.

Truck Maintenance Costs

As we’re sure you can imagine, carrying out the points we mentioned above in our truck maintenance tips can be costly to resolve.

A recent study in the US states that truck maintenance costs can amount to nearly £12,000 per year, when you take into account repairs, tyre replacements, and general ongoing maintenance that operating a truck in the UK requires.

One of the most significant benefits of hiring or leasing a truck from Mac’s Trucks is that all of these truck maintenance costs are included in your monthly price.

This means you know exactly how much your truck will cost you each month, without the headache of repairs and maintenance to consider should something happen to your vehicle.

What’s more, we manage and plan your maintenance meaning you don’t have to organise getting your truck in at a garage, we’ll simply book your checks in at a time that works for you.
