A cracked windscreen is a small problem but poses significant safety risks and legal concerns. If you’re wondering whether it’s safe to keep driving with a cracked windscreen or if it’s legally permissible, you’re not alone. Let’s break down the key factors to help you understand the risks and what’s required for cracked windscreens.
1. Understanding Windscreen Damage
Understanding your vehicle’s windscreen and how it can be damaged is not just crucial, it’s empowering. It’s not just a protective barrier from external elements but also a key component in maintaining the structural integrity of your vehicle. Any crack or chip, regardless of size, can impact its strength and functionality. This knowledge empowers you to make informed decisions about your vehicle’s safety.
How Windscreen Cracks Happen
Windscreen cracks can occur for many reasons, such as stones hitting the glass, severe weather, or sudden temperature changes. Regardless of the cause, any crack or chip should not be ignored, as it can compromise your safety and vehicle performance.
Types Of Cracks
Windscreen cracks vary in size and location. Chips might seem like a small issue, but even a minor crack can develop into something more serious. Various types of cracks include:
Star Cracks:
Often caused by impacts, these look like a star-shaped pattern.
Stress Cracks:
These appear without any impact and are usually due to temperature changes or pressure on the glass.
2. Safety Concerns Of Driving With A Cracked Windscreen
A cracked windscreen is more than just a superficial issue. Here’s why driving with a cracked windscreen can pose significant dangers:
A Reduced Visibility
Any crack in your windscreen can obstruct your view, making it harder to see clearly while driving. This is especially true when the crack is in the driver’s line of sight. Reduced visibility can lead to poor decision-making, slower reaction times, and accidents.
Weakened Windscreen Strength
The windscreen provides structural support to the car, especially in a collision. A cracked windscreen can protect you in an accident but can shatter easily under pressure or impact, making the vehicle less safe for the driver and passengers.
Airbag Deployment
The windscreen plays a crucial role in the correct deployment of airbags. In a crash, a cracked or damaged windscreen may not allow the airbag to deploy correctly, putting occupants at greater risk of injury.
3. Legal Aspects Of Driving With A Cracked Windscreen
While driving with a cracked windscreen has profound safety implications, legal factors must be considered. The law tends to focus on two key areas when it comes to windscreen damage:
Roadworthiness Requirements
Most road safety laws, including car windscreen damage laws, require vehicles to meet specific standards to be considered roadworthy. A cracked windscreen can affect this requirement depending on the size and location of the crack. A windshield that impairs visibility or is in a position that could interfere with the vehicle’s operation is considered unsafe.
Inspection And Fines
Driving with a cracked windscreen could result in a fine or the vehicle being deemed unfit for the road. If your vehicle is inspected and the windscreen damage is considered hazardous, you may be ordered to have it repaired or replaced.
Defects And Penalties
Depending on the severity of the crack, a vehicle can be flagged as having a “major defect,” leading to penalties or fines. If the crack is in an area that significantly reduces the driver’s visibility or compromises safety, it could result in fines and a requirement to fix the damage immediately.
4. When To Repair Or Replace The Windscreen
If you notice any cracks or chips in your windscreen, acting quickly is essential. Whether you need a repair or a complete replacement depends on the following factors:
Size Of The Crack
Minor chips or cracks (less than 3cm in diameter) can often be repaired without a complete replacement. Cracks larger than 15cm, particularly those of greater length, are more likely to necessitate windscreen replacement services.
Location Of The Crack
Cracks or chips in the driver’s line of sight are much more dangerous and can make repairs more difficult. Any damage near the edges of the windscreen or in the central view should be addressed immediately.
The Age Of The Vehicle
Older vehicles may be more susceptible to cracking or chipping, as the windscreens might be weaker or more prone to damage. Regular maintenance checks are essential in these cases.
5. How To Repair Or Replace A Cracked Windscreen
Fixing or replacing a cracked windscreen might appear complex, but it’s a simple process when managed by professionals. Here’s what you need to know:
Repairing The Windscreen
If the crack is small, a professional can often inject resin into it to fill it and restore the strength of the glass. This can be done quickly and may prevent the crack from spreading further. However, repairs may not be suitable for all types of cracks.
Replacing The Windscreen
For more significant or serious cracks, a complete replacement may be required. If the crack compromises the integrity of the glass or obstructs visibility, replacing the entire windscreen is necessary. This will ensure the vehicle is roadworthy and safe to drive.
6. Tips For Preventing Windscreen Damage
While it’s impossible to avoid cracks altogether and chips, there are some simple steps you can take to prevent windscreen damage:
Replacing The Windscreen
Maintaining a safe distance from other vehicles and huge trucks, as stones or debris from their tyres can cause cracks in your windscreen.
Avoid Extreme Temperatures
Rapid temperature changes, such as pouring hot water on a cold windscreen or using the heater immediately after turning on the car, can cause the glass to crack.
Conclusion
Driving with a cracked windscreen is neither safe nor legal. A damaged windscreen can affect visibility, weaken the vehicle’s structural integrity, and prevent airbags from functioning correctly. Addressing windscreen damage promptly is not just essential, it’s your responsibility to ensure your safety and comply with legal requirements. At Singh Auto Care, we recommend taking immediate action if you notice a crack or chip and being proactive about regular windscreen maintenance to avoid potential issues.
