Q:

Restricted sight distance and large total intersection volume can result in which type of accident?

A) Overturn B) Fixed object
C) Right-angle D) Rear-end
 
Answer & Explanation Answer: C) Right-angle

Explanation: Restricted sight distance and large total intersection volume can result in Right-angle collisions at unsignalized intersections. These accidents can be avoided by installing signals and restricting parking near corners.

Q:

Inadequate shoulder on a road can result in which type of accident?

A) Overturn B) Fixed object
C) Right-angle D) Rear-end
 
Answer & Explanation Answer: A) Overturn

Explanation: Inadequate shoulder on a road can result in an overturn. Other possible causes can be roadside or pavement features. Flattening slopes and ditches and relocating drainage facilities can help be done to avoid these types of accidents.

Q:

What is a collision diagram?

A) A schematic diagram of collision of two vehicles that occur during turning movements B) collision when two vehicles coming at right angles collides with each other and bifurcates in a different direction
C) A schematic diagram of collision of more than two vehicles D) A schematic diagram of collision of two vehicles that occur after turning movements
 
Answer & Explanation Answer: A) A schematic diagram of collision of two vehicles that occur during turning movements

Explanation: A collision diagram is a schematic diagram of collision of two vehicles that occur during turning movements. In a collision diagram, each collision is symbolized by a set of arrows to indicate the direction.

Q:

The direction of vehicles after an angular collision depends on ______

A) initial speeds of the two vehicles and their weights B) final speeds of the two vehicles and their weights
C) the angle at which they collide D) the type of vehicle
 
Answer & Explanation Answer: A) initial speeds of the two vehicles and their weights

Explanation: The direction of vehicles after an angular collision depends on the initial speeds of the two vehicles and their weights. Collision diagrams are used to identify similar accident patterns.

Q:

What is an angular collision?

A) Collision when two vehicles coming at right angles collides with each other and bifurcates in a different direction B) Collision when two vehicles coming at 60 degrees angles collides with each other and bifurcates in a different direction
C) Collision when two vehicles coming at 30 degrees angles collides with each other and bifurcates in a different direction D) Collision when two vehicles coming at 180 degrees angles collides with each other and bifurcates in a different direction
 
Answer & Explanation Answer: A) Collision when two vehicles coming at right angles collides with each other and bifurcates in a different direction

Explanation: Angular collision is a type of collision when two vehicles coming at right angles collides with each other and bifurcates in a different direction. The diagram consists of an outline map showing the direction of movement of vehicles and pedestrians involved in accidents.

Q:

Poisson impact theory divides impact into how many parts?

A) 2 B) 3
C) 4 D) 5
 
Answer & Explanation Answer: A) 2

Explanation: Poisson impact theory divides impact into 2 parts and they are compression and restitution. The compression phase in this theory is cited by the deformation of the cars. It follows Newton’s law F = ma.
