Xueshan Tunnel Vehicle Regulations and Penalties Quick Guide

Xueshan Tunnel (National Freeway No. 5) is a closed-type long tunnel, with extremely strict vehicle regulations and penalties for violations, enforced through comprehensive technological surveillance. Key regulations and penalties are summarized as follows: • Traffic Restrictions: Only small passenger cars and large buses are allowed. Large trucks, motorcycles, and vehicles carrying hazardous materials are strictly prohibited. Violators will be fined NT$3,000 to NT$6,000. • Driving Speed: The maximum speed limit is 90 km/h, and the minimum speed limit is 70 km/h. Speeding or driving too slowly in normal traffic flow (road train leader) will result in a fine of NT$3,000 to NT$6,000. Severe speeding (130 km/h or more) can incur fines up to NT$36,000 and license plate suspension. • Safety Distance and Lanes: Lane changes are prohibited throughout the entire tunnel (crossing double solid white lines). During normal driving, small passenger cars must maintain a distance of 50 meters, and large buses 100 meters, from the vehicle ahead. Violating lane change rules or failing to maintain a safe distance will result in a fine of NT$3,000 to NT$6,000. • Lights and Breakdowns: Headlights must be turned on when entering the tunnel. Violators will be fined NT$3,000 to NT$6,000. If a vehicle breaks down due to lack of fuel, battery issues, or a flat tire, a fine of NT$600 to NT$1,200 will be imposed (excluding towing fees). • Aggressive Tailgating (Reckless Driving): Following too closely to the vehicle ahead or flashing lights to intimidate in the tunnel will result in a fine of NT$6,000 to NT$36,000, license plate suspension for 6 months, and mandatory traffic safety education. Serious offenses may lead to prosecution for coercion or endangering public safety.
