Montana Driver's Ed Practice Test

A solid yellow line on your side of the road indicates that no passing is allowed. This means that drivers should not cross the line to overtake another vehicle. The purpose of this marking is to enhance safety by preventing drivers from attempting to pass in areas where visibility may be limited or where conditions are not safe for passing. This could be on curves, hills, or in other situations where there may be oncoming traffic that a driver cannot see.

The choice that suggests passing is allowed with caution is incorrect because a solid yellow line specifically designates that passing is prohibited, regardless of the circumstances. Likewise, the option that relates to a bike lane or the one requiring only trucks to stop do not pertain to the meaning of a solid yellow line in this context, as they refer to different regulations and road markings.
