Explanation:

Question 19

Warning signs are typically diamond - shaped (or square - shaped rotated 45 degrees) and have a yellow background with black symbols or text. Regulatory signs are often white, red, black, etc., with different shapes (like octagonal for stop signs). Guide signs are usually green or blue with white text and rectangular. Interstate signs are shield - shaped. So the correct option is related to warning signs.

A red "X" over a lane (like in a lane - use control signal) means that travel in that lane is prohibited. This is a standard traffic signal rule. So the statement is true.

On an expressway, the right lane is generally for slower - moving vehicles or those entering/exiting the expressway. Fast - moving vehicles use the left lanes. Bicyclists are not allowed on most expressways. So the right lane is for slower - moving vehicles.

Answer:

b) Warning signs
