It’s an interesting coincidence that North Dakota is increasing its interstate speed limit to 80 mph just as neighboring states South Dakota and Montana have done the same. You can now legally drive faster than before even before all the new signs are up, but this change comes with stricter fines and varying speed limits in cities, stirring debate on whether higher speeds will impact overall road safety. What this means for drivers and enforcement is worth examining closely.

North Dakota Speed Limit Laws

Key Takeaways

  • North Dakota’s interstate speed limit increased to 80 mph effective August 1, 2025, aligning with South Dakota and Montana.
  • New speeding fines are either $20 or $5 per mph over the limit on highways ≥ 65 mph, with an extra $20 for speeding over 16 mph above the limit.
  • Speeding fines in construction zones with workers increased from $80 to $150 to enhance safety.
  • Urban area speed limits reduced, e.g., Dickinson, Grand Forks, and Jamestown lowered from 75 to 70 mph, West Fargo limited to 55 mph[BACKGROUND].
  • Sign replacements for the new limits begin August 4, 2025, expected to take about two weeks to complete statewide[BACKGROUND].

Updates to Interstate Speed Limits in North Dakota

Although the new interstate speed limit in North Dakota officially takes effect on August 1, 2025, you can legally drive at 80 mph even before the updated signs are installed, which will start being replaced on August 4 and take about two weeks to complete.

The interstate speed limit increase to 80 mph aligns North Dakota with South Dakota and Montana, addressing the current average speed of 81 mph already logged.

While speed limits in certain cities decrease to 70 mph, the state has raised speeding fines, particularly in construction zones, aiming to reduce traffic fatalities despite the higher speed allowance.

New Structure of Speeding Fines and Penalties

North Dakota has implemented a new speeding fine structure that charges you $20 or $5 for each mile per hour over the limit on highways with speed limits of 65 mph or higher, whichever amount is greater. For lower speed zones, fines are $20 or $3 per mph over the limit. Exceeding the speed limit by more than 16 mph adds a $20 penalty. Construction zone fines increased from $80 to $150 to improve public safety and deter aggressive speeding. This system aids law enforcement by simplifying fine calculations and reinforcing speed limit compliance.

ConditionFine Structure
Highways ≥ 65 mph$20 or $5 per mph over limit (greater)
Lower speed zones$20 or $3 per mph over limit (greater)
Excessive speeding (>16 mph)Additional $20
Construction zonesMinimum fine increased to $150

This approach balances penalties to target aggressive speeding and protect workers in construction zones across North Dakota.

Adjustments in Speed Limits Within City Areas

You’ll notice North Dakota is reducing speed limits in several city areas to improve safety where traffic is heavier.

This means slower zones in places like Dickinson, Grand Forks, and Medora, as well as extended lower limits around Bismarck, Fargo, and West Fargo.

These expanded slow zones aim to protect drivers and pedestrians by adjusting speeds in denser urban settings.

Reduced Urban Limits

While speed limits on rural interstates have increased to 80 mph, several urban areas in North Dakota have seen their limits reduced to improve safety.

In Dickinson, Grand Forks, Jamestown, Valley City, and Medora, the speed limit has dropped from 75 mph to 70 mph.

West Fargo’s limit is now set at 55 mph, extending to the Sheyenne Street exit.

Bismarck and Fargo already have lower urban interstate limits, which are now extended under new legislation focused on safety.

New signs reflecting these changes will be installed within two weeks to enforce updated speed limits effectively.

Expanded Slow Zones

Because urban areas have unique traffic patterns and safety concerns, expanded slow zones now adjust speed limits more precisely within city limits.

In North Dakota, speed limits will decrease from 75 mph to 70 mph in Dickinson, Grand Forks, Jamestown, Valley City, and Medora starting August 1, 2025.

Bismarck and Fargo’s existing lower limit zones are expanding, with Bismarck’s slower limit extending to Exit 161 and West Fargo’s 55 mph zone now including the Sheyenne Street exit.

Installation of new signage will begin on August 4, 2025, taking about two weeks to improve safety in these urban areas.

  • You’ll notice safer driving conditions where speed limits are lowered.
  • The new signage will clearly mark these expanded slow zones.
  • Bismarck and Fargo residents will benefit from extended lower limit areas reducing risk.

Comparison of North Dakota’s Speed Limits With Neighboring States

You’ll notice North Dakota’s new 80 mph interstate speed limit matches those in South Dakota and Montana, reflecting a regional trend toward higher limits on these highways.

In contrast, Minnesota keeps a lower 70 mph limit on its rural interstates, highlighting different state approaches to speed and safety.

This variability stems from distinct traffic conditions and legislative priorities across neighboring states.

Interstate Speed Limits

North Dakota will raise its interstate speed limit to 80 mph starting August 1, 2025, matching the limits already set by South Dakota and Montana.

This change reflects regional traffic conditions and safety considerations, bringing North Dakota’s limits in line with neighboring states while remaining distinct from Minnesota’s 70 mph limit.

Before the increase, North Dakota’s limit was 75 mph.

  • Imagine smoother, faster commutes across North Dakota’s vast highways
  • Feel the alignment with regional traffic trends and neighboring states’ standards
  • Acknowledge safety with improved fines encouraging compliance and caution

Regional Speed Variations

Eight states, including North Dakota, South Dakota, and Montana, have established 80 mph speed limits on their interstate highways, reflecting a growing regional trend toward higher maximum speeds in areas with suitable traffic and road conditions.

North Dakota’s new 80 mph interstate limit, effective August 1, 2025, aligns it with these neighboring states but contrasts with Minnesota’s 70 mph rural limit.

These variations result from differing traffic patterns, rural conditions, and safety priorities shaped by state legislation.

North Dakota balanced increased speed limits with stricter fines to address safety concerns within this regional context.

Safety Concerns and Impact on Traffic Incidents

Although higher speed limits can improve travel times, they significantly raise safety concerns by increasing the risk and severity of traffic incidents. In North Dakota, speed or aggressive driving contributed to about one-third of the 96 fatal crashes in 2023, and 1,427 injuries were linked to these factors.

With the new 80 mph speed limit taking effect in August 2025, drivers must recognize that increased speeds demand longer following distances for safe stopping. Vulnerable road users, including motorcycle riders and construction workers, face heightened risks as speed limits rise, which underscores the critical need for caution and adherence to traffic safety.

  • Each 5 mph increase exponentially raises crash severity, putting lives at greater risk.
  • Speeding-related crashes disproportionately endanger those without vehicle protection.
  • Allowing insufficient following distances at high speed reduces reaction time dramatically.

Legislative Process Behind the Speed Limit Changes

While increasing the interstate speed limit to 80 mph, the North Dakota legislature crafted House Bill 1298 to balance improved traffic flow with safety concerns by raising fines and simplifying enforcement.

Signed by Governor Kelly Armstrong, the bill raises the interstate speed limit from 75 to 80 mph effective August 1, 2025. It introduces a streamlined fine structure for speeding violations to aid law enforcement and increases minimum fines in construction zones from $80 to $150 to bolster public safety.

The legislative process involved compromises reflecting concerns about speed, fines, and worker protection on North Dakota interstate highways.
