The Risks of Driving with Obstructed Windshields
Last Updated on 2 May 2026
People fail to have their obstructed windshields repaired for several reasons. For one, the crack may be very small, and they do not believe that a crack that small could possibly be a problem. The truth is, a small crack expands with every slam of the door, a change of weather or vibrations from driving down the road. The most common reason that people fail to repair cracks is because of the cost, but they are not acknowledging a few facts. The first is that the crack is currently small enough to only require a few inexpensive repairs. If they continue to ignore this situation, it could turn into something that requires a full windshield replacement. Let’s examine the issues that an obstructed windshield can cause.
An Increased Distraction
It is difficult to maintain your attention on the road when a crack catches your eye. Even when you take one short second to look at a crack, you can miss a red light signal or a sudden stop. You may even fail to see an obstruction in the road because of the momentary distraction that a crack can cause. This can lead to collisions that cause devastating injuries and serious property damage.
Dirt
Surprisingly, a dirty windshield is enough to lead to car collisions. This occurs when a windshield is so dirty that the driver cannot adequately see the road. White markings on the road may be invisible when this is the case. As a result, the driver may not be able to navigate his or her correct path.
Simple dirt can also alter how the light shines through the windshield. For example, it may create a glare that makes it difficult for the driver to see properly. Ensuring that the windshield is clean is one simple way to prevent the likelihood of car collisions. This just requires you to wash your car on a regular basis.
While driving, dirt can be kicked up and sprayed across the windshield. The best thing to do in this instance is to pull over to the side of the road. Then, you can do your best to clean the windshield before you continue on to your destination.
Cracks
When a windshield is cracked, the driver cannot see through it as easily. The crack may be small or even a tiny chip, but it can be a distraction for you. These tiny imperfections may also obscure what is on the road. After the sun goes down, chips and tiny cracks can distort how the light enters through the windshield. This makes it much harder to see everything within your path.
The Risk of Shattering
A windshield that has a crack is weaker than one without, so every time you drive the vehicle, there is a risk that the crack can shatter. Even if the crack remains small for a while, temperature changes can cause it to grow wider. This is what will occur as the weather gets warmer, and the air conditioning abruptly lowers the temperature.
Many other movements also increase the possibility of a crack increasing and shattering. For example, all it takes is driving over a pothole or a speed bump. It may even happen when you close your door too hard. All of these movements send vibrations through the glass, and this causes the crack to spread instantly. If the glass shatters, you and your passengers are at risk of being injured.
Penetration of Moisture and Dirt
When there is a crack in the windshield, moisture and dirt can seep into the windshield’s layers. Delamination begins when this happens, as the windshield’s layers begin to separate. This makes it even more difficult for you to see through your windshield, and it also weakens the glass. It leads to the type of damage that requires a full windshield replacement.
Airbag Malfunction
In order for the airbags to properly inflate, they require a structurally sound windshield. They must send the airbags in the direction of the driver and the passenger, but they may not do this as effectively with a cracked windshield. When the airbag deploys, it uses a tremendous amount of force, but a compromised windshield may not be able to withstand it. For this reason, the airbag may inflate at the wrong angle, or it may deflate too early. Because of this, the airbags will not be as effective at preventing injury during a collision.
Inadequate Roof Support
If the vehicle were to roll over, a weakened windshield would be incapable of supporting the roof. Therefore, the roof would cave in, and this creates a very dangerous situation for those inside the vehicle.
Because a cracked windshield does not help maintain the structural integrity of the vehicle, it can easily shatter during a collision and leave the passengers vulnerable to being thrown outside. When victims have been thrown from the vehicle, they suffer the most catastrophic injuries, including fatal road rash, severe lacerations, internal organ damage, broken bones, paralysis and traumatic brain injuries.
Road Safety Regulations
Every state has road safety regulations, and when you drive with a cracked windshield, you may be breaking those regulations. If you are caught driving with a cracked windshield, you may receive a fine or a penalty in your state. In some states, a law enforcement officer can pull you over for a cracked windshield and issue you a citation. This is where fines and penalties may come in, and it may even lead to an increase in your insurance premiums.
If the motorist who injured you in a car collision had a cracked windshield, you are entitled to hold that person accountable by hiring a car accident lawyer. This matter requires the expertise of a well-trained and knowledgeable attorney who is equipped to provide legal support for car accident victims. Crashes involving defective vehicles are highly complex legal matters, and you need a lawyer with the training and knowledge to represent you in court.
