Ministry of Transport Regulations

A MOT can be either a normal check or something to be dreaded, something that can result in a long list of essential expenses, based on the type of vehicle you have, how old it is and what condition it’s in. While it may be common knowledge that a faulty engine, damaged exhaust or other technical problems can lead to our cars failing an MOT, the condition of your windscreen can also affect whether you pass or fail the MOT test based on Ministry of Transport Regulations.

Depending on a number of factors, the outcome of your MOT can be affected by a chip or crack in your windscreen. This article examines the Ministry of Transport Regulations in detail and offers tips on how windscreen problems can be avoided or rectified.

What is a MOT test?

A “MOT” refers to this Department for Transport test. Most vehicles over three years old have an annual inspection, or MOT test, to make sure they are roadworthy, safe and do not emit harmful pollutants.

The country’s approved test centers, each of which has a legal blue symbol with three white triangles, conduct MOT inspections. A MOT involves numerous vehicle inspections, including examinations of your vehicle’s brakes, fuel system, lights, mirrors, seat belts, windshield wipers, and exhaust system. The Ministry of Transport Regulations are what we’ll be discussing.

What is a MOT test?

When does a crack means fail?

Ministry of Transport Regulations state that if a windscreen crack is in the driver’s field of vision, the limit for the size of the damage is 10 mm. This is a 290mm wide vertical section of the windscreen just above the steering wheel.  Any vehicle with a chip in this area larger than 10mm will fail the MOT and you will need to have it repaired or replaced before you can retake the test.

Penalty Points for Ministry of Transport Regulations

Your windshield is divided into 2 zones to follow Ministry of Transport Regulations. Different rules apply to chips and cracks in these zones:

The part of the windscreen in front of the driver is called zone A. The center of the zone is above the steering wheel. If there are any chips or cracks in this area that are more than 10 mm in diameter, your MOT will fail.

Zone B refers to the remaining part of the windscreen. In terms of Ministry of Transport Regulations, you will fail your MOT if the windscreen has additional damage of 40mm or more in diameter. The exact location of the damage is the most important difference between the two zones. Tiny cracks in the driver’s field of vision can be a significant driving hazard, but the problem is less severe in other areas of the windscreen.

Although cracks in Zone B may not be a failure, your inspector will still see them. It’s usually a good idea to get a tiny chip or crack repaired as soon as possible, because even the smallest chips can get worse and more dangerous very quickly.

Will the windscreen wipers fail the MOT?

Your MOT inspector will be looking for more than just Ministry of Transport Regulations. The condition of your windscreen wipers is also taken into account during an MOT test.

  • You will fail your MOT if your wipers are broken, loose or not working properly.
  • Windscreen wipers are essential for maintaining a clear windscreen, which is essential for driving safety. Even the shortest journey can be dangerous if they fail to do this properly.
  • Your windscreen washer fluid is an easy item to overlook. Your wipers and washers work together to keep your windscreen clear and dirt-free. Insufficient washer fluid, clogged or blocked nozzles will result in a MOT failure.

It is definitely worth checking both your windscreen wipers and windscreen washers in advance, as they will both be tested during the MOT. Make sure you get any problems fixed before your MOT as they are some of the easiest car components to fix yourself. It is well worth the time and effort to do something as simple as replacing your windscreen wipers or topping up your windscreen washer fluid.

There is a 40mm restriction on the remaining part of the windscreen that is swept by the wipers. Therefore, if the passenger side window has a crack smaller than this, it will not normally result in a failure. However, if there is a risk that the crack will get worse and lead to a failure, the inspector may advise you to find a garage to have the windscreen repaired.

Driving with a cracked windscreen

Another factor to bear in mind is that driving a car in an unsafe condition, such as with a cracked windscreen, can be an offence. The Highway Code requires drivers to have a clear view of the road ahead. It also stipulates that the glass must be in good condition, so if you are stopped by the police and the vehicle is found to be in poor condition, you could face points on your license and a fine.

Things can get even worse if you have an accident while driving with a cracked windscreen.  This is because it’s obvious that you were at fault for the collision because the windscreen of your car was damaged and you shouldn’t have been driving it.

How can I prevent the crack in my windscreen from getting worse?

Never ignore a crack or chip in your car’s windscreen, no matter how small. A cracked windscreen is often the result of a chip that was ignored and later developed into something more serious. The damage won’t go away on its own.

Minor damage can be repaired more quickly and at a lower cost than a completely broken windscreen, which usually needs to be replaced.

It is best to repair the chip or crack as soon as possible. Don’t put off repairs even if the damage is out of sight; if left unattended, a crack can quickly develop across the entire windscreen.

Epoxy or acrylic adhesive can be injected into a chip to fix it in place. This seals the chip to keep out dirt and moisture. However, larger cracks can’t be repaired as quickly and require a more extensive windscreen repair.

Prepare your windscreen for the MOT test

To sum up, let’s look at some of the things you need to be aware of regarding mirrors and cracked windscreens MOT rules before your MOT test.

Your vehicle must have clear mirrors that allow you to see what’s behind you in order to pass the MOT. If these mirrors are cracked or significantly damaged, have them repaired immediately. The same applies to your interior rear-view mirror.

Drivers need to be able to see what’s next to and behind them, and front side windows make this possible. With this in mind, make sure they are well cleaned or, if they are badly damaged or scratched, replace them.

Rear side windows don’t give the driver as much information as the windscreen and front side windows, so damage to them is less of a concern.
