What Do Mud Flaps Do?

Mud flaps are like shields for your car.

They stop rocks and dirt from hitting the car’s body.

Remember, when you drive on wet roads, water can spray onto other cars and other people.

Mud flaps play a crucial role in safeguarding by catching the water and sending it down to the ground.

They also work to prevent rocks and gravel from being thrown up by your tires, which could potentially damage other vehicles.

This way, everyone stays dry and safe.

How Mud Flaps Are Made

Mud flaps are created to keep dirt away from your car. So the material used has to be durable and resilient.

Generally, most are made of one of two materials with the exception of custom cases.

Most will be made of rubber or plastic. The placement is just behind the wheels of your vehicle in the arches.

The rubber ones are stretchy and strong, while the plastic ones are lighter and don’t break easily.

Rubber Vs Plastic

what do mud flaps do?

Rubber is a popular material for mud flaps because it is flexible, durable, and resistant to damage from debris and the elements.

Rubber mud flaps can be molded to fit specific vehicles and are often designed to be easy to install and remove.

Although very durable, the rubber becomes brittle over time and can deteriorate.

Plastic mud flaps are popular because they are lightweight and resistant to cracking and fading.

They are often less expensive than rubber mud flaps and can be customized with different colors and designs.

Custom VS Universal Design

Mud flaps are available in both custom and universal designs.

Custom mud flaps are designed to fit specific vehicles and are often molded to match the contours of the wheel well.

They provide maximum protection and are often made of high-quality materials that are designed to last.

Universal mud flaps are designed to fit a wide range of vehicles and are often less expensive than custom mud flaps.

They are available in a variety of sizes and shapes and can be trimmed to fit different vehicles.

However, they may not provide as much protection as custom mud flaps and may not be as durable.

Laws about Mud Flaps

what do mud flaps do?

Different states have rules about mud flaps. Most say big trucks need them to keep the roads clean and safe.

State Laws

Each state in the US has its own set of regulations regarding mud flaps on vehicles.

A majority of states require mud flaps on commercial vehicles, and the specific requirements can vary.

For instance, Alaska’s mud-flap requirements are intended to protect other vehicles from water and debris that may be kicked up from a vehicle’s tire, particularly where the vehicle and tires are oversized.

The mud flap must extend downward to a distance of 14 inches from the ground, as measured when the vehicle is standing over level ground.

To be on the safe side, general guidelines recommend that mud flaps don’t hang more than 6 inches from the ground.

Most states that require mud flaps on commercial vehicles mandate their use if they are licensed, registered, and capable of operating on public roads at speeds of more than 25 miles per hour.

If you are curious about any of the other 41 states’ specific rules regarding mud flap laws, check the Department of Transportation website for that particular state.

Commercial Vehicle Regulations

The Federal Motor Carrier Safety Administration (FMCSA) recommends mud flaps be mounted at 300 mm and at an angle greater than 22 degrees.

Most jurisdictions simply state that the vehicle must have mud flaps/splash guards on the rear of the vehicle that is adequate to keep spray and debris tossed up by the tires from hitting the windshields of following traffic.

Specific requirements may vary depending on the vehicle’s size, weight, and type.

Most state regulations follow the Society of Automotive Engineers (SAE) recommended practice that the mud flap be at least the full width of the tire and that the bottom of the mud flap is no more than 1/3 the distance from the center of the rear tire to where the mud flap is located.
