Is It Safe to Drive With a Cracked Windshield? What Washington State Drivers Should Know

Seeing a cracked windshield around Clark County has become increasingly common. Many drivers assume it’s just a cosmetic issue—or something they can deal with “later.” But in reality, even a small crack can quickly turn into a safety concern, especially during colder months.

So, is it safe to drive with a cracked windshield? The short answer: sometimes—but often not for long.

Here’s what Washington drivers should know.

Why Windshields Matter More Than You Think

Your windshield isn’t just there to block wind and rain. It plays a critical role in:

• Structural strength of your vehicle

• Proper airbag deployment

• Clear visibility in all weather conditions

• Advanced safety systems like lane-departure cameras and collision-avoidance sensors

A compromised windshield can weaken all of these systems—sometimes without obvious warning signs.

Is It Illegal to Drive With a Cracked Windshield in Washington?

Washington law doesn’t specify exact crack sizes, but it does require drivers to maintain clear visibility.

You may be cited if:

• A crack obstructs the driver’s line of sight

• The damage causes glare or distortion

• The windshield is considered unsafe by an officer

In short: if it interferes with safe driving, it can be an issue—even if you haven’t been pulled over yet.

Why Cracks Get Worse (Especially in Winter)

Many drivers are surprised by how fast windshield damage spreads. Common causes include:

• Cold temperatures causing glass to contract

• Defrosters rapidly heating one area of the glass

• Road vibrations from potholes and rough pavement

• Moisture seeping into chips and expanding

What starts as a small crack can turn into a full windshield replacement in days—or even overnight.

Safety Risks You Might Not Expect

Driving with a cracked windshield can lead to:

• Reduced visibility during rain or night driving

• Improper airbag deployment in an accident

• ADAS camera errors or system shutdowns

• Increased risk of shattering during a collision

Modern vehicles rely on the windshield more than ever—especially those with forward-facing cameras.

Repair or Replacement: How Do You Know?

A windshield may be repairable if:

• The chip is small and not spreading

• Damage is away from the driver’s line of sight

• There are no long cracks

A replacement is usually necessary if:

• The crack is growing

• Damage is near the edges

• Visibility is affected

  

• Safety systems are involved

An inspection is the best way to know for sure.
