Benefits of a Car Window Breaker

  • Prepare for emergencies. Anything can happen when you're traveling, and you may get into an accident. Sometimes cars automatically lock the doors, which can trap you inside. A car window breaker will enable you to break the side window and crawl out of the car.
  • Prepare for severe weather. A car window breaker can come in handy if you live in a region that experiences severe weather changes, such as storms, floods, or heavy snow. You will have peace of mind knowing that you can break out of your car if the weather takes a turn for the worst. 
  • Save lives. Side window and windshield breaker tools are an essential item in a safety tool kit, especially for first responders such as firefighters, paramedics, police officers, rescuers, and emergency medical technicians. It helps to remove car crash victims trapped in their cars and is faster than kicking out the window.

Key features

Construction Quality

A car window breaker needs to be strong enough to break through a car window and durable enough to withstand repeated action. The best car escape tools are made of stainless steel, which is a durable material, and other hard metals. Tools with plastic cases may break when too much force is applied to them. 

Design

The car survival tool shouldn't be a burden to carry around or lift. You need a lightweight and portable design that can fit in your pocket or your vehicle’s center console. Keep in mind that you may be a bit unconscious or dizzy following an accident, and you need something that you can swing easily.

Performance Style

The performance or window breaking style should save you from vehicular entrapment within the shortest time possible. A hammer style technique could take minutes and a lot of effort before you break the window. The best glass breakers have an automatic spring mechanism that easily breaks the glass in seconds. 

Other Considerations

  • Car Window Type: You need to ensure that the safety tool is designed to break through the type of glass your car window has. Most units can break through a standard tempered glass in the side window, but you need to find a stronger tool to break a double-layered glass windshield. 
  • Ease of Use: Simplicity is key when it comes to auto emergency escape tools. There's no point in buying a gadget with overly complex features. You may forget how to use it when you are in panic mode. You need a tool that uses minimal force and takes a short time to break a window. 
  • Auxiliary Features: Select a tool that offers multiple safety features on top of a car window breaker, including a sharp knife, alarm, flashlight, and a mounting system for easy accessibility. These extra features can come in handy for frequent campers.

Best Car Window Breaker Overall: Resqme The Original Keychain Car Escape Tool

Resqme The Original Keychain Car Escape Tool
Amazon

This Resqme car window breaker includes a built-in seatbelt cutter that helps you make a quick escape if you’re trapped in your seat. The stainless steel razor is carefully concealed within the unit. You only have to pull out the clip that holds it back, and it can cut through a seat belt with just one hard swing. It also has a spring-loaded stainless steel spike that shatters the side window once you press the blackhead on one spot of the glass and release the spring-loaded spike. 

This tool attaches to a key holder with a detachable clip, and you can use it to hold your car keys. You can easily pull it away from your car keys when you need it the most. You can use a cable tie to attach it to the rearview mirror so that your passengers can also use it. The gadget also comes in handy for removing children who are stuck in a booster seat. This safety tool is useful for all car owners and first responders.

A major drawback of the product is that it has poor-quality construction. First, it's difficult to remove the blade clip without the support of a cable tie or the key chain. You may break the tool in that moment of struggle. The spring mechanism gets weaker with frequent use, and it may fail when you need it the most. Moreover, most of the metal parts aren’t rust-resistant.

BlueSkyBos Car Safety Escape Hammer
Amazon

The BluSkyBoss is an affordable multi-purpose emergency tool that offers a number of lifesaving functions. The unit runs on two AA batteries, includes a flashing beacon, an LED flashlight, and an alarm siren that will help call attention to you or a trapped vehicle when there’s no one in sight. It also has a steel window breaker that’s shaped like a hammer. It's designed to break through one layer of tempered glass by hammering into the side window.

Another helpful feature is that the seatbelt cutter will help you get out of a jammed seatbelt. The tool only weighs 3.2 ounces and is compact enough to be stored in the central console, glove box, or door pocket. This tool can help you break out of a sinking car, a vehicle that’s on fire, or a car that’s rolled over and the power windows aren’t functioning. It's also great for camping outdoors and is a handy tool for traveling emergencies.

Also, the hammering technique isn’t very efficient for helping a trapped victim to escape in seconds, and it's difficult to thrust underwater. You may receive a defective product upon delivery, and the unit doesn’t come with batteries. Moreover, it may develop lighting issues in wintry weather. Despite that, this escape tool is recommended for rescue workers and firefighters.

Tips

  • If you are trapped in your car but can’t find your car window breaker, use the headrest to break the window. Most car models have detachable headrests. However, don’t use this as an excuse not to get the proper tools. A headrest may jam, and you don’t want to struggle with it when you don’t have time to spare.
  • Get a full emergency kit for your car with a first aid kit, a fire extinguisher, and car seat belt cutter for emergency situations. If you have a penknife, it may help you cut through the seatbelt if it gets stuck, but it won't be strong enough to help you break through the glass.
  • Always place your emergency tools in an accessible spot in case you are trapped in your seat. The best spots to store the car window breaker are on the side of the driver's door, on the center console, on the visor on the driver’s side, or under the driver’s seat.

FAQs

Q: Is it dangerous to shatter a car window?

A: It depends on the type of glass breaker you are using. Hammer glass breakers tend to break the glass in huge chunks that may cut you if you aren't too careful. Automatic glass breakers are less dangerous because the glass shatters into tiny pieces. You should wear gloves or cover yourself before you break the window. If you are saving someone in a trapped car, advise them to look away before you break the glass.

Q: Can you break bulletproof glass with a glass breaker?

A: Bullet-resistant glass is designed differently than normal tempered glass. It has several layers of polycarbonate with glass making up the external layer. A glass breaker may break the outer glass layer but won't break the window. Instead, you would have to have a siren alarm and an LED flashlight to send a distress signal. Also, always have your phone nearby, and invest in a head unit that can send an emergency signal in case you're trapped. 

Q: Can a glass breaker work on laminated glass?

A: Laminated glass has plastic in between two layers of glass. It is hard to break with a glass breaker, even if it has an automatic spring mechanism unless it's a high-quality tool with a strong spring. Hammer glass breakers are better at the job but require extra time and effort.
