New Hampshire sits in the Northeast census region, with Concord as its capital and Manchester and Nashua among its largest cities. This guide collects the New Hampshire driving laws people search for most, covering speed limits and phone use to insurance, car tax and motorcycles.
Every topic below covers one law in detail, with the facts, the figures and how it compares nationally with sources; data was reviewed October 25, 2026.
New Hampshire driving laws: speed limits
The top speed limit in New Hampshire is 70 mph. Interstates are posted at up to 65 mph in both rural and urban areas.
| New Hampshire: Maximum posted speed | 70 mph |
|---|---|
| Rural interstates | 65 mph |
| Interstates in cities | 65 mph |
70 mph is posted on part of I-93 in the north of the state.
On busy roads such as I-93 and I-89, posted limits are frequently lower than 70 mph, especially around Manchester and in work zones.
Motorists also need to keep a speed that is safe for the conditions, even when that means going slower; police can cite unsafe speed on its own.
In short, under New Hampshire driving laws: max speed limit, 70 mph.
New Hampshire driving laws: cell phone and texting law
Only hands-free. New Hampshire has a hands-free law: drivers are not permitted to hold a phone to make calls or send messages behind the wheel. Voice calls through the car and a mounted map are fine.

|---|---|
| Texting while driving (all motorists) | Banned |
| Total phone ban for teens | Drivers under 18 |
Under the New Hampshire driving laws, a dash-mounted phone, voice commands and one swipe to pick up a call or start navigation stay legal; picking it up, even at a red light, is what gets ticketed.
Teen drivers face more: in New Hampshire, motorists under 18 may not use a phone at all, hands-free included.
In short, under New Hampshire driving laws: phone law, hands-free law.

New Hampshire does not require car insurance for the majority of drivers, but you must be able to pay for damage you cause. If you buy a policy, it must meet 25/50/25 plus medical payments and uninsured motorist coverage.
New Hampshire is an at-fault state, so the driver who causes a crash is responsible for the other parties' injuries and damage via their liability insurance.
A minimum policy rarely covers a serious crash, since hospital bills and a new car may top $50,000 fast.
Consumer groups suggest limits like 100/300/100, as anything above your limits may be taken from your savings.
