Louisiana Traffic Laws and How Sideswipe Crashes Happen

Driving in Louisiana comes with important rules that keep everyone safe. These rules help drivers, walkers, and families share the road without danger. But crash studies and safety reports show a clear link between certain traffic violations and sideswipe crashes in Louisiana.

What Is a Sideswipe?

A sideswipe happens when the side of one car scrapes or bumps the side of another car while both cars are moving. Imagine two kids walking in a school hallway. If one kid drifts sideways and bumps the other kid’s shoulder, that is like a sideswipe. Cars do the same thing when a driver does not stay in the right lane or does not look before moving over.

Why Sideswipes Happen — Traffic Violations

In the 2024 crash data for Louisiana from the Center for Analytics & Research in Transportation Safety (CARTS), there are several driver violations that often lead to crashes — including sideswipe-type crashes. Some of the most common actions include:

Failed to keep in proper lane — drifting out of the lane can cause a sideswipe.
Disregarded other road markings — ignoring lane markings may lead to moving into another vehicle’s side.
Failed to yield right-of-way — when one car moves into another’s path unexpectedly, sideswipes may result.
Careless driving / inattentive operation — not paying attention can cause drifting or sudden moves.

Driving Rules You Must Follow

Follow the Speed Limit

Speed limit signs tell you how fast you can drive. Slower speeds help you stop in time and prevent crashes. In Louisiana, the speed limits vary by road type:

On interstates or controlled-access highways the maximum is 70 mph.
On multi-lane divided highways with partial or no access control the limit is 65 mph.
On smaller, two-lane undivided rural roads the limit is typically 55 mph.
In residential or business areas, or school zones, the limits are much lower (often 25-35 mph or even less) depending on local posting.

Stop at Signs and Lights

Red lights and stop signs mean you must stop. Look both ways before you move again. This helps prevent crashes on busy streets in Baton Rouge and Gonzales.

Stay in Your Lane

Stay inside your lane lines. Use your turn signal if you want to turn or change lanes. This simple rule can prevent most sideswipe crashes.

Wear Your Seatbelt

Everyone in the car must wear a seatbelt. Seatbelts protect you during sudden stops and crashes. Children must ride in the right car seat or booster seat for their age and size.

Do Not Drive After Drinking

Louisiana does not allow driving if alcohol or drugs make you unsafe. Alcohol can slow your thinking and make crashes more likely.

No Texting While Driving

Texting while driving is against the law. Looking down for even a second can cause a wreck. Keep your eyes on the road and your hands on the wheel.

Use the Left Lane Only to Pass

Louisiana drivers must use the left lane only to pass another vehicle. Move back to the right lane when you finish passing. This keeps traffic flowing safely.

Keep Your Car in Good Shape

Your car must have working lights, mirrors, brakes, and license plates. A clean windshield helps you see better during rain or fog. Learn more about seasonal car safety checklist here.

Carry Insurance and Registration

Drivers must carry proof of insurance. All vehicles must be registered with the state.

Watch for School Zones and Emergency Vehicles

Slow down in school zones during posted hours. Move over when you see police, firefighters, or other emergency workers stopped on the road.

Why This Matters for Louisiana Drivers

Louisiana has many busy roads where cars travel side by side. Crash research shows that sideswipe wrecks often happen when a driver breaks simple lane rules. Staying alert, using signals, and keeping steady in your lane can protect you, your passengers, and the community.
