• Cars, SUVs, and Jeeps: These vehicles are typically well-suited for NH-37, provided they are in good condition and properly maintained. Four-wheel-drive vehicles can be advantageous, especially during the monsoon season or in areas with rougher road surfaces.
• Buses: Both public and private buses are common on NH-37, connecting towns and cities along the route.
• Trucks and Lorries: Heavy goods vehicles (HGVs) are essential for transporting goods between Assam and Manipur. However, there may be weight restrictions on certain sections of the highway, and these vehicles must adhere to traffic regulations and speed limits.
• Tankers: Tankers carrying fuel, oil, or other liquids are permitted, but they must comply with safety regulations for transporting hazardous materials.
• Motorcycles and Scooters: While allowed, riders should be extremely cautious. NH-37 can have sections with poor road conditions, heavy traffic, and winding roads. Wearing a helmet is mandatory, and riders should prioritize visibility and defensive driving.
• Three-Wheeled Vehicles (Auto-Rickshaws/Tuk-Tuks): The permissibility of these vehicles can be variable. They are more likely to be allowed in urban or semi-urban sections of the highway but may be restricted from longer stretches, particularly those with high-speed traffic.
• Oversized Vehicles: Vehicles exceeding standard size or weight limits may require special permits to use NH-37. They might also be subject to specific routing and timing restrictions to minimize disruption to traffic flow.

National Highway 37 (NH 37) is a vital roadway connecting Assam to Manipur, playing a crucial role in enhancing regional connectivity and facilitating economic growth. Spanning approximately 450 kilometers, this highway traverses diverse landscapes, including lush green hills and valleys, significantly influencing trade and transportation in Northeast India. NH 37 serves as an essential link for the movement of goods and services, promotes tourism, and supports the livelihoods of local communities by providing easier access to urban markets. Additionally, the highway aids in fostering cultural exchanges between Assam and Manipur, enriching the sociocultural fabric of the region. Despite its importance, NH 37 faces challenges such as seasonal flooding, landslides, and maintenance issues, which can affect travel safety and efficiency. Ongoing government initiatives aim to upgrade and improve the infrastructure of this highway, ensuring it meets the growing demands of traffic while enhancing safety and accessibility. The successful development of NH 37 will not only bolster local economies but also strengthen the strategic link between these two northeastern states, supporting broader national integration and fostering regional cooperation. Ultimately, the continuous improvement and maintenance of National Highway 37 is pivotal for the sustainable development of the northeastern region of India.
