Special vehicles must make stops and park **off the roadway and shoulder** for several reasons:

- **Traffic safety and flow**: Parking on the roadway or shoulder can obstruct the passage of other vehicles, creating dangerous situations and hindering traffic flow. This is especially important on roads where space is limited and traffic is constant.

- **Avoiding dangerous situations**: Stopping or parking in places such as curves, hill crests, tunnels, level crossings, and near intersections can be very dangerous. These places are critical for visibility and the safe movement of all road users.

- **Compliance with regulations**: Traffic regulations prohibit stopping and parking in areas that may interfere with the use of the road by other vehicles or pedestrians, such as lanes reserved for buses, taxis, bicycles, and areas for people with disabilities.

- **Adequate space**: By parking off the roadway and shoulder, it is ensured that the vehicle does not obstruct the passage of other vehicles or interfere with the visibility of traffic signals.

For these reasons, it is essential that special vehicles make stops and park off the roadway and shoulder to ensure safety and order on the roads.
