Louisiana Driving Laws (2026): Speed Limits, Insurance and More
Louisiana sits in the South census region, with Baton Rouge as the capital and New Orleans and Baton Rouge among its largest cities. This page gathers the Louisiana driving laws motorists ask about most, covering speed limits and phone use through coverage, taxes, inspections and riding.
Each section below explains one rule in full, with the facts, the figures and how it compares nationally; we last verified the figures on October 25, 2026 for Louisiana.
Louisiana driving laws: speed limits
The highest speed limit in Louisiana is 75 mph. Rural interstates are posted at up to 75 mph and urban interstates up to 70 mph.
| Louisiana: Highest posted limit | 75 mph |
|---|---|
| Rural freeways | 75 mph |
| Interstates in cities | 70 mph |
On major roads such as I-10 and I-12, signs are often lower than 75 mph, especially through New Orleans and in work zones.
Every driver must also hold a speed reasonable for weather and traffic, even when that means going slower.
In short, under Louisiana driving laws: max speed limit, 75 mph.
Louisiana driving laws: cell phone and texting law
Only hands-free. Louisiana enforces a hands-free law: anyone driving are not permitted to hold a phone to call, text or scroll behind the wheel. Voice calls through the car and a mounted map are fine.
| Louisiana: Holding a phone while driving | Banned |
|---|---|
| Sending texts while driving | Banned |
| Teen phone ban | Drivers in their first year of licensing |
Louisiana's hands-free law (HB 519, 2025) has been enforced with tickets since January 1, 2026.
Under the Louisiana driving laws, a dash-mounted phone, spoken commands and a single tap to take a call or start navigation are permitted; holding the phone in traffic is what gets ticketed.
Young motorists get a stricter rule: in Louisiana, drivers in their first year of licensing cannot use a phone while driving, not even through Bluetooth.
In short, under Louisiana driving laws: phone law, hands-free law.
Louisiana driving laws: driving age and teen licenses
In Louisiana, teenagers may apply for a learner's permit at 15 and a provisional license at 16, which still restricts night driving and passengers.
| Louisiana: Permit age | Age 15 |
|---|---|
| Provisional license | Age 16 |
| Supervised driving hours | 50 (15 at night) |
| All limits lifted | Age 17 |
To qualify for the road test, teenagers in Louisiana log 50 hours (15 at night) of supervised driving.
At a glance, under Louisiana driving laws: learner's permit age, permit at 15.
Louisiana driving laws: minimum car insurance
Louisiana sets a minimum of 15/30/25 in liability coverage: $15,000 for injuries to one person, $30,000 for all injuries in one crash and $25,000 for property damage.
| Louisiana: Bodily injury per person | $15,000 |
|---|---|
| Bodily injury per accident | $30,000 |
| Damage to property | $25,000 |
| Also mandatory | None |
| Fault system | At-fault |
| Must you insure | Yes |
Louisiana follows the at-fault system, so the at-fault driver is responsible for the other motorists' injuries and damage through liability coverage.
A minimum policy often falls short in a serious crash, since hospital bills and a new car can exceed $30,000 quickly.
Advisers often recommend limits like 100/300/100, since anything above your limits can be claimed from you personally.
At a glance, under Louisiana driving laws: car insurance, 15/30/25.
Louisiana driving laws: car sales tax
Louisiana collects a 5% state sales tax on car purchases, and local taxes can come on top.
| Louisiana: State-level rate | 5% (sales tax) |
|---|---|
| City or county tax | Yes, in some areas |
| Trade-in deducted | Yes |
| Example: $30,000 car | $1,500 |
The state rate rose from 4.45% to 5% in January 2025. Parish and city taxes are added on top.
- A $19,800 car in Louisiana: around $990 in state tax
- A $34,700 car in Louisiana: roughly $1,735 in state tax
- A $55,000 car in Louisiana: roughly $2,750 in state tax
A trade-in lowers the Louisiana driving laws: a $30,000 car with a $5,000 trade-in owes around $1,250 compared with $1,500.
Bottom line, under Louisiana driving laws: car sales tax, 5%.
Louisiana driving laws: vehicle inspection and emissions
Yes. Louisiana requires an annual safety inspection and emissions testing in five parishes in the Baton Rouge area.
| Louisiana: Safety inspection | Every year |
|---|---|
| Emissions testing | Some areas: five parishes in the Baton Rouge area |
A law signed in June 2026 (HB 1085) ends the annual "brake tag" inspection for most personal vehicles on January 1, 2027, replacing it with a $6 QR code tied to registration. Emissions tests continue in the Baton Rouge area.
The safety check in Louisiana covers brakes, lights, tires, steering, glass and horn once a year.
Smog checks on recent models read the on-board computer, which takes a few minutes; a lit check-engine light typically means a failure.
Bottom line, under Louisiana driving laws: car inspection, safety + emissions.
Louisiana driving laws: license and registration deadlines for new residents
After moving to Louisiana, you have 30 days to obtain a Louisiana driver's license, and 30 days to register your car.
| Louisiana: New driver's license | 30 days |
|---|---|
| Plate deadline | 30 days |
| Minimum car insurance | 15/30/25 |
| Vehicle check | Safety + emissions |

Bottom line, under Louisiana driving laws: new resident deadline, 30 days.
Louisiana driving laws: motorcycle helmet law
Yes. Louisiana has a universal helmet law: each rider and each passenger need to wear a DOT-approved helmet, regardless of age. That holds on I-10 and I-12 just as it does on local streets in New Orleans.
| Louisiana: Who must wear a helmet | All motorcyclists and passengers |
|---|---|
| Kind of law | Universal |
| Adults can ride without a helmet | No |
Under the Louisiana driving laws, operators and passengers of any age must wear a helmet on any motorcycle, including mopeds that require an endorsement.
Crash research suggests that helmets cut 37% of rider deaths in crashes, and around 41% for passengers.
A compliant helmet carries the DOT label on the back; novelty helmets that lack it do not count.
Bottom line, under Louisiana driving laws: helmet law, all riders.
Louisiana driving laws: lane splitting
No. Riding between lanes are not legal in Louisiana. A motorcycle is entitled to a full lane, and riders may not pass between vehicles or ride on the lane line.
| Louisiana: Riding between moving lanes | Not legal |
|---|---|
| Lane filtering (stopped traffic) | Not legal |
| Law dates from | — |
Because no statute permits it, Louisiana driving laws counts as an illegal pass, and a crash while doing it can count against the rider with insurers.
At a glance, under Louisiana driving laws: lane splitting, not allowed.
