The MOT test is a legal requirement for vehicle ownership in the UK. Beyond basic factors, a vehicle’s MOT result can be influenced by natural elements, particularly weather. As conditions shift, vehicle performance may decline, raising the risk of test failure. Whether in freezing winters or hot summers, weather can cause hidden issues that vehicle owners must recognise to prepare for the test. This blog discusses how changing weather affects vehicle performance and MOT outcomes. Let’s begin and help owners prepare their vehicles for the MOT in any weather.
Impact of Winters on Battery and Electrical Components
Winter weather is an enemy to a vehicle’s battery and electrical systems. Reliable battery and electrical performance are essential for passing the MOT Bridgend. As temperatures fall, the battery’s chemical reactions slow, reducing its ability to hold a charge and forcing the engine to need more power to start. This puts extra strain on older batteries and can lead to abrupt battery failure. Dashboard warning lights signal electrical issues or weak batteries. Faulty headlights, taillights, or other vehicle lights can also cause the vehicle to fail. Drivers should thoroughly inspect all electrical components before heading to the test centre.
Impact of Cold Weather on Tyres
The next component that is highly impacted during winters is the tyres. As the temperature drops, the tyre pressure will also drop, which will result in a bad grip on the surface for the vehicle and can lead to uneven tyre wear. As the tyres will be underinflated, the tread will fail the test, and the tyres might also not meet the UK government’s safety standards. The risk of cuts, punctures, or sidewall damage to tyres will also increase in conditions such as snow, ice, or wet roads. The problem does not end here. As the temperature drops, the rubber compound of tyres will also harden up, which will reduce their flexibility and tyre’s traction to the surface. As a result, the tyres will deteriorate much faster. By conducting regular tyre pressure inspections and checking for any hidden damage, the chances of the vehicle failing the test will also reduce during winter.
Rain Causing Rust and Corrosion
The two greatest threats to tyre condition are rust and corrosion, mainly caused by rain, slush, or road salt. Components such as the suspension, brake lines, and exhaust system become highly susceptible to rust. Because drivers rarely inspect the underside of their vehicles, rust often develops unnoticed. During inspections, examiners check for corrosion. If a critical component or a nearby area is rusted or corroded, the vehicle will fail immediately. The best way to prevent rust and corrosion is to thoroughly wash and clean beneath the car, especially in winter. Some also use protective coatings to minimise long-term damage.
Impact of Wet Conditions on Braking System
Winter is also an enemy of the vehicle’s braking system. Factors like water, mud, or salt buildup around the discs or pads can cause rapid wear of the braking system and reduce its effectiveness. That’s why drivers should keep an eye out for issues like squeaking or grinding when the brakes are pressed. If these problems are ignored, then the chances of failing the MOT will increase, as the vehicle won’t be considered safe to drive. To ensure that the vehicle is fully prepared to battle the cold winter conditions, drivers can get a car servicing Bridgend done, as it will help take care of the conditions of all the components of the vehicle.
Reduce Impact of Weather on a Vehicle
The most effective solution requires drivers to let their vehicles reach testing conditions through vehicle acclimatisation. After spending extended time in cold weather or heavy rainfall, the system experiences temporary changes in its performance. It affects the brake and suspension and exhaust system. A brief drive before the MOT examination assists in eliminating moisture while bringing each system to its regular function.
Rubber and seals require your complete focus. The extreme temperature conditions lead to faster deterioration of wiper blades, door seals and tyres, which an MOT test evaluates thoroughly. The application of lubricant to hinges, locks and exposed joints should be done regularly. It protects against stiffness which results from cold and damp weather conditions.
The best approach to scheduling MOT tests is to choose dates with stable weather conditions to help reduce temporary weather effects which would interfere with testing results.
Conclusion
Natural factors like weather are beyond your control, but you can take care of your vehicle. As they help in determining the working condition of the vehicle, the results of a vehicle’s MOT will also be impacted. Here, a detailed breakdown of the impact that cold and wet weather conditions will have on a vehicle and its components is provided. So, make the required checks on the vehicle and have yourself an MOT-ready vehicle.
