A solid yellow line indicates that passing is prohibited. A dashed yellow line indicates that passing is allowed. White lines separate lanes for which travel is in the same direction. A double white line indicates that lane changes are prohibited.

Chevrons are most often used on the outside of a curve or the narrowing of a road. For the striped designs, the stripes should point down – to indicate the direction for the traffic to pass an obstruction.

A broken white line marks the middle of the road. When this line becomes longer, and the gaps get smaller, this means that there is a hazard close ahead. You should not cross this line unless you can see that the road ahead is clear and you wish to overtake another vehicle or turn off the road.

Solid yellow center lines indicate two-way traffic moving in opposite direction with no passing allowed. Always keep to the right of the yellow line. Broken yellow center line means passing is permitted in either direction.
