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.

Moffet Forklift Mounted To Read of Curtainsider Truck

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.

What is a curtainsider?

A curtainsider truck, also known as a Tautliner, gets it’s name from the curtains that feature on the sides of the vehicle where a traditional box trailer would be.

Curtainsiders come in a variety of sizes from 7.5 tonne up to 26 tonne and are mainly used for the transportation of goods across from various sectors. The goods are packaged and transported on pallets and are unloaded from the side by a forklift truck.

Features of Curtainsiders

Curtainsider trucks come with a range of abilities that make them perfect for use in the transportation and logistics industries, including:
Easily and efficiently transport goods

Designed for easy and efficient loading and unloading, the curtains that feature on curtainsiders work on runners that live along the top and bottom of the trailer. Along the bottom of the trailer, load retaining straps are tightened whilst in transit, to ensure the curtain doesn’t blow in the wind and stops the cargo from slipping sideways.

When the goods reach their destination, the load retaining straps are undone, the curtain is pull opened by a forklift truck and the goods are unloaded.
Euro 6 compliant engines

The euro emission standards came about in 1992, with the first being Euro 1. The standards are there to help reduce the levels of harmful exhaust emissions that vehicles emit. Newer models of trucks feature Euro VI engine technology – something we guarantee when hiring a vehicle from Mac’s.

Euro VI engine technology is designed to reduce these emissions through special filters that feature within the engine. These filters convert dangerous Nitrogen Oxide into water vapour and nitrogen. Thanks to the filters, the engines emit a third of the C02 and 20 times less NOX when compared to older engines.
Multi drop deliveries

Due to the rigid nature of traditional box trailers, once the trailer is loaded, you cannot gain access to the goods at the middle or the back until the front had been unloaded.

Curtainsider trucks take away the last on first off delivery process associated with traditional box trailers. Thanks to their curtain sides, they allow you to have easy access to all the goods and palettes on board regardless of what order they have been loaded on, making them ideal for multi drop deliveries.

Curtainsider contract hire

Here at Mac’s Trucks, were contract hire specialists and have a wide range of high quality vehicles including Curtainsiders that are available on both short and long term contract hire.

Contract hire can benefit your business in a range of financial and operational ways and we work with you to create a curtainsider truck hire plan that works for your business, and is fit for both the purpose and timeframe needed, other benefits include:

Cost effective: Contract Hiring a truck allows you to spread the cost either on a weekly or monthly basis. You can hire the truck you need without having to purchase the vehicle outright, resulting in lower monthly payments as your monthly costs are calculated to cover the vehicle’s depreciation, not the full cost. However, long term leasing also gives you the same branding options as purchasing does, meaning you can have your custom livery across the vehicle.

Repair and maintenance inclusive: Both repair and maintenance costs are included within our contract hire plans, so there’s no need to worry if the worst was to happen to your curtainsider truck, as we’ll repair at no extra cost. Plus, our curtainsider trucks are inclusive of our 6 week mandatory maintenance checks, we’ll just arrange the checks to be taken care of at a time that suits you.

No hidden extras: Your monthly costs are fixed – and we guarantee that for the length of your contract. Therefore if you should ever have any trouble with your vehicle, we’ll make sure it’s fixed as soon as possible, whilst providing you with a replacement vehicle in the meantime.
