MOT Pass Rates: What the Latest Data Reveals

The latest data on the UK's Ministry of Transport (MOT) tests is in, and it paints an interesting picture of the nation's driving habits and the condition of its vehicles. From average mileage that's still reflecting pandemic-era changes to fluctuating pass rates across the year, this data offers valuable insights for every driver. We'll delve into what these figures mean for your car, your insurance, and when you should ideally book your next MOT.

Average Mileage Still Reflects Lockdown Levels

For years, the UK's average annual mileage had been on a downward trend. However, the pandemic significantly accelerated this. What's notable is that even now, years after the lockdowns ended, average mileage remains at those significantly reduced levels. In 2023, the national average nudged up slightly to 6,551 miles per year, a figure virtually identical to that recorded in 2020. This suggests a fundamental shift in daily life, with people driving less than they did pre-pandemic. Over the last decade, average mileage has fallen by a considerable 12%, equating to a reduction of 1,097 miles annually compared to 2012. This indicates a long-term behavioural change rather than a temporary blip.

Understanding Averages: The Mean vs. The Mode

It's crucial to understand that 'average' can be interpreted in different ways, and the 'mean' can be skewed by a few individuals driving exceptionally high mileages. A more representative measure for understanding the driving habits of the majority is the 'mode'. When we look at mileage in brackets of 1,000 miles, the most common bracket for UK drivers is actually between 3,000 and 4,000 miles. This means that while the 'mean' mileage is 6,551 miles, a statistically average person is likely driving much less. Someone driving the mean mileage would fall into only the 6th most common bracket, highlighting that a significant number of drivers cover less than the "average" mileage.

The Impact on Car Insurance

The rising cost of living has impacted many aspects of car ownership, including insurance premiums. The cost of car parts, repairs, and replacement vehicles has increased significantly, often outpacing inflation. Coupled with a rise in car crime and subsequent claims, this has led to a general increase in car insurance costs. For drivers who cover lower mileages – and as the data suggests, this is a substantial portion of the driving population – opting for pay-by-mile car insurance could offer significant savings. It's always advisable to get a quote to see if this type of policy fits your driving habits and budget.

Mileage by Fuel Type

The data also reveals interesting patterns in mileage based on a vehicle's fuel type. Generally, drivers of petrol cars tend to drive less than the national average. This could be linked to the fact that electric and hybrid vehicles, often more expensive upfront, are more commonly owned by higher-income households, who historically tend to drive more. Conversely, vehicles with very low average mileages include those running on Compressed Natural Gas (CNG) and Liquefied Natural Gas (LNG).

MOT Pass Rates Dip Slightly

The overall MOT pass rate has seen a slight decrease, falling from 78.1% to 76%. It's plausible that as mileage begins to climb back up after the significant lows of recent years, vehicles are experiencing a bit more wear and tear, contributing to this trend. However, for newer vehicles aged 3-5 years, pass rates have remained relatively stable at approximately 89%. This suggests that while the general fleet might be showing more signs of age, newer cars continue to perform well in their first MOTs.

The Best Time to Book Your MOT

The data consistently shows that MOT pass rates tend to increase as the week progresses. Pass rates rise by about 9.4% from Monday to Sunday. While fewer testing centres are open on weekends, which can skew the figures, the trend holds even when controlling for testing volume. For instance, Friday typically sees a higher pass rate than Monday, despite similar testing levels. Therefore, if your MOT is due, consider booking it towards the end of the working week for a potentially better chance of a pass. You can use online checkers to determine when your MOT is due.

Seasonally, winter months, particularly October and November, see pass rates dip below 75%, with December and January not faring much better. Conversely, March, July, and September tend to have higher pass rates, often exceeding 77%. While the timing of bookings can be influenced by when a car's MOT is due, there's a clear advantage to having your test between spring and summer. An interesting anomaly was the 92.7% pass rate on December 24th, 2023, though this was due to a very low volume of tests, making it an outlier rather than a reliable indicator.

Manufacturer and Model Performance (3-5 Year Old Cars)

When analysing cars aged 3-5 years, which can indicate inherent build quality, Japanese manufacturers continue to dominate the top performers. For 2023, Lexus, Porsche, Honda, and Suzuki all featured in the top ranks, with Mazda replacing Toyota in the top 5. The consistent high performance of these manufacturers suggests a strong emphasis on reliability and build quality.

Top Performing Models (3-5 Year Old Cars)

On the flip side, the bottom performers for 3-5 year old cars are a mix of European manufacturers, with British and French brands featuring prominently. Notably, all of the bottom five manufacturers saw a dip in their pass rates compared to the previous year. MG and Vauxhall, along with Citroen, Renault, and Tesla, were among the lower-ranking manufacturers.

Bottom Performing Manufacturers (3-5 Year Old Cars)

The bottom five models for cars in the 3-5 year age bracket are predominantly French and British. The Vauxhall Combo has entered this list, replacing the Mercedes Vito. Models like the Peugeot Partner, Citroen Berlingo, Vauxhall Vivaro, and Renault Trafic all feature, with most showing a slight decrease in their pass rates. The Renault Trafic saw a minor improvement of 0.2%.

The Influence of Car Colour

Interestingly, car colour can also play a role in MOT pass rates, though the reasons are often statistical rather than technical. For cars aged 3-5 years, turquoise has retained its top spot for a second year, boasting a 93.3% pass rate. Maroon and yellow follow, with gold in fourth place. The higher pass rates for less common colours like turquoise are likely due to smaller sample sizes, making the statistics less robust. For more common colours, red achieved a respectable 91% pass rate. Multi-coloured cars, despite their rarity, had the lowest pass rates, possibly due to a higher propensity for accidents among vehicles with more flamboyant aesthetics.
