Platoon is a group of vehicles that move on the road together in close proximity. Vehicles speed in Platoon is almost equal. In the platoon, there will always be a vehicle trying to overtake another vehicle in front of the vehicle. To overtake the vehicle, driver must know the distance ahead for overtaking. Overtaking sight distance (Jd) is the distance that allows a vehicle to overtake another vehicle in front of the vehicle safely until the vehicle returns to its original lane. Based on the problems above, this research needs to be carried out with the aim of knowing the sight distance of overtaking vehicles in the platoon to overtake other vehicles and the potential of lane width widening base on the potential of the vehicle do the overtaking and based on the existing regulation. Data collection is done by recording traffic conditions using a handy cam. The Handy cam is placed on a tripod and in a safe place, which can properly record traffic conditions at a predetermined survey location. As the result, the maximum, average and, minimum speed during off-peak hours were higher than the speed at peak-hour conditions for Buttinggi-Padang and Padang-Bukttinggi direction. The majority of the vehicle (more than 50%) have the potential to overtake another vehicle. The segment road that was studied is the National, Arterial Primary Road. The existing lane width is 5.5 meter, each direction is 2.25-meter, undivided road. If there is a vehicle that will overtake another vehicle, the vehicle will take the path of the vehicle from the opposite direction. If the vehicle will overtake another vehicle, the driver must pay attention to the vehicle from the opposite direction. Based on the Law on Roads No. 38 of 2004, the width for primary arterial roads is 7 meters. Based the existing regulation and the safety, it was recommended to do the lane width widening on this segment road.
