12 feet.
When within 100 feet (about five car lengths) of or crossing an intersection or railroad crossing.
If you have a double-yellow stripe in the center of the road, then you are not allowed to pass. Same rule applies to a single yellow stripe, or when a solid line is on your side and a dotted line on the other.
When within 100 feet (about five car lengths) of or crossing an intersection or railroad crossing.
Passing or to avoid an obstruction in the roadway, but it must be done safely.
In North America, to pass only
In general no. The intersection of two parallel half-planes A and B is either a half-plane (either A or B, when A and B have similar orientation) or the empty set (when A and B have opposite orientation). When A and B are not parallel, their intersection is a maximal open region bounded by the two lines that define A and B, respectively. In this case, the intersection always exists and it is never a half-plane.
A lot would depend on the roadway and the chosen vehicle among other factors. Somewhere between 2 and a half and 3 hours is a reasonable guess.
There are 5,280 feet in a mile, so half a mile is half that, or 2,640 feet.
One half yard equals one and one half feet because there are three feet in one yard, so half of three feet is one and one half feet.
Since there are 5280 feet in 1 mile there are 2640 feet in half a mile.
The ratio is 2/3: One foot can be expressed as 2 half-feet and one and a half feet can be expressed at 3 half-feet.
A yard is three feet, so half a yard would be one and a half feet.
