On a **two-way interurban road**, stopping or parking on the left side is not allowed under any circumstances. This is because, on roads outside towns and cities, you must stop and park on the **right side** of the road, leaving the shoulder free as much as possible. This rule is applied to ensure safety and the proper flow of traffic on two-way roads, where parking on the left side could obstruct circulation and increase the risk of accidents.

Additionally, there are specific places where stopping and parking are prohibited, such as in curves, tunnels, level crossings, and other places where visibility or space to maneuver is limited. These restrictions reinforce the importance of always parking on the right side on two-way interurban roads to avoid dangerous situations.
