Do Snow Chains Help Prevent Crashes in Snow and Ice?

February 9, 2026

Missouri winters can swing from mild to treacherous in a matter of hours, and when snow and ice settle across the roads, drivers look for ways to stay safer behind the wheel. One winter-driving topic that remains a topic of debate is whether snow chains actually help prevent crashes.

Although snow chains were more common decades ago, modern vehicles now come equipped with 4WD or AWD systems, traction control, and all-weather or winter tires; features that reduce the need for chains in everyday conditions. However, snow chains remain useful in certain situations, especially in rural, hilly, or unplowed areas where tire grip is limited.

And remember, if you were injured in a winter-weather crash caused by another driver’s negligence, a St. Louis car accident lawyer at our law firm can help you understand your rights and explore your options for compensation.

How Snow Chains Work

Snow chains are metal links that wrap around a vehicle’s tires to increase grip on compact snow and ice. The chains dig into the frozen surface, reducing wheel slip and helping with starting, stopping, and climbing steep terrain.

They’re most effective when roads are covered in several inches of packed snow. On partially cleared or fully plowed roads, however, chains can become more of a hazard than a help.

Pros of Using Snow Chains:

Improved Traction on Deep Snow and Ice: Chains create friction, helping tires maintain control when they would otherwise spin or slide.

Better Braking Ability: Stopping distances are shorter compared to standard all-season tires on icy or snowy surfaces.

Added Control on Hills and Rural Roads: Drivers who live in or travel through less-maintained areas may find chains beneficial for navigating steep, unplowed roads.

Emergency Support: If you unexpectedly encounter difficult conditions, chains can help you get out of a stuck situation or safely reach a plowed road.

Cons of Using Snow Chains:

Limited Use on Bare Pavement: Chains should never be used on dry or mostly dry roads; they can damage your vehicle, tear up the roadway, and reduce handling.
Speed Restrictions: Most snow chains require drivers to maintain a speed of 30 mph or less. On highways or busy roads, this can pose a risk if other drivers are traveling at higher speeds.

Not Compatible with All Vehicles: Some vehicles, especially those with low wheel-well clearance, are not compatible with snow chains. For example, many sedans and newer SUVs are subject to manufacturer restrictions.

Harder on Tires and Suspension: Extended use increases wear and can affect alignment or strain suspension components.

Labor and Learning Curve: Chains require proper installation and removal, which some drivers find stressful in cold and snowy conditions.

How To Install and Remove Snow Chains

If you choose to use snow chains, they must be installed correctly for proper control. Here is a quick overview of how to put them on and remove them safely:

Installing Snow Chains:

Lay the chains flat on the ground and untangle them.
Drape them over the tire, ensuring even distribution on both sides.
Roll the vehicle forward a few feet to expose the remaining tire surface.
Connect the hooks and tensioning system according to the manufacturer’s instructions.
Tighten and recheck them after driving a short distance.

Removing Snow Chains:

Pull over to a safe, flat location.
Unhook or release the tensioners.
Lay the chains flat and back the vehicle off them slowly.
Inspect for damage before storing.

Installation difficulty varies by chain design, and practicing at home can make winter conditions easier to handle.

Are Snow Chains Worth It for Most Drivers?

For most Missouri drivers, especially those in St. Louis, snow chains are not usually necessary thanks to:

AWD/4WD systems
Traction control and stability systems
All-weather or dedicated winter tires
Regularly plowed and salted major roads

However, snow chains can still be valuable if you:

Live in a rural or hilly area
Drive on unplowed private or gravel roads
Frequently encounter deep snow
Need emergency traction during a storm

Chains improve traction, but they aren’t a substitute for safe driving, proper tires, or good judgment. Most modern drivers will rely more on winter tires than chains, but chains remain a useful backup in certain conditions.
