intersections? $($Select all that apply.$)$

$($a$)$ yield sign

at roundabout approaches to control traffic on the approaches

a separate or channelized right turn lane without an adequate acceleration lane

a minor road when it intersects a major road, at an unsignalized intersection, with approximately equal

traffic volumes, and where minimum volume or crash warrants are met

a minor road when it intersects a major road, at an unsignalized intersection, with significantly different

traffic volumes, and where a combination of high speed, restricted view, and serious crashes indicate

the necessity for such a control
