Driving in Indiana

Indiana (IN) sits in the Midwest region, with Indianapolis as its state capital. Handheld phone use behind the wheel is banned.

Tyre Requirements in Indiana

There is no winter tyre mandate in Indiana, though having season-appropriate tyres is strongly recommended. Tire chains are permitted when road conditions require them.

Studded Tyres: Allowed October 1 through April 30.

Tread Depth: Indiana enforces the federal minimum of 0.0625 inches (2/32"). At this depth, wet braking performance is severely compromised. Replace tyres at 4/32" — do not wait for the legal limit.

Given Indiana’s cold winters with lake-effect snow in the north, consider switching to winter tyres if you regularly drive in cold or snowy conditions. Summer tyre compounds harden below 45°F (7°C) and lose grip.

Insurance and Equipment in Indiana

Indiana requires all drivers to carry liability insurance. Keep proof in your vehicle. If you are stopped without it, penalties include fines and possible licence suspension.

Required vehicle equipment in Indiana: functioning headlights, brake lights, turn signals, at least one rearview mirror, a horn, windshield wipers, and valid registration plates. Check Indiana’s specific window tint limits before adding aftermarket tint.

Licence Requirements for Visitors to Indiana

A valid licence from your home state or country is accepted for driving in Indiana. International visitors are strongly advised to carry an IDP alongside their national licence. Rental agencies and police in Indiana may request both.

New residents of Indiana must get a state licence after establishing residency. Requirements usually include a vision screening, a written test on Indiana’s traffic laws, and possibly a behind-the-wheel exam.

Toll Roads in Indiana

Toll facilities in Indiana increasingly use cashless electronic tolling. Rental cars may come with a transponder option, but the daily fee adds up quickly. Consider getting your own transponder if driving extensively in Indiana.

Seasonal Driving in Indiana

Driving conditions in Indiana are shaped by cold winters with lake-effect snow in the north.

Seasonal preparation for Indiana:

• Check Indiana’s DOT website for real-time road conditions and travel advisories

Renting a Car in Indiana

Most rental agencies in Indiana require drivers to be at least 21. Under-25 surcharges are standard. If you hold a foreign licence, bring your IDP and confirm acceptance when booking.

Before leaving the lot in Indiana, photograph any existing damage, test the lights, wipers, and horn, and verify that the spare tyre and jack are present. Check the fuel policy — most agencies expect a full tank on return.

Your existing insurance or credit card may cover rental vehicles in Indiana — verify before declining the agency’s coverage. International visitors should strongly consider full coverage.

Emergency Contacts in Indiana

Dial 911 for any emergency in Indiana — police, fire, or medical. For non-emergency roadside assistance, contact the Indiana State Police.

If you are in an accident in Indiana: stop immediately, check for injuries, call 911 if anyone is hurt, move vehicles to the shoulder if safe, exchange insurance and contact details, and photograph the scene. Do not admit fault.
