Vehicle Dynamics
A vehicle parked on a flat surface with brakes set is an example of this type of traction.
What is stationary (static) traction?
The two types of standard brakes.
What are drum brakes and disc brakes?
You can not force this. You can not assume this. You do not have this automatically.
What is the Right of Way?
Parking intelligently, giving audible notice, use a spotter, understand signals, use side mirror, check front corners, and maintain speed controls should all be done while doing this basic maneuver?
What should be done while Backing Up?
This is the area between the incident space and the adjacent travel lane.
What is the Lateral Buffer Space?
The force that tends to make a rotating body move away from the center of rotation.
What is Centrifugal Force?
Systems that enable the driver to stop the vehicle in the shortest possible distance on a slippery surface while maintaining control and avoiding a skid. These prevent the wheels from locking, keeping the tires turning so there is friction with the road surface, allowing directional control.
What are Antilock Braking Systems (ABS)?
1. Aim high in steering. 2. Get the Big Picture.3. Keep eyes moving, scan.4. Make sure the other drivers see the emergency vehicle. 5. Identify an Escape Route
What are the five visual habits of emergency driving?
These are the three types of intersections.
What are controlled, uncontrolled, and special (such as a roundabout).
Turning the front wheels of vehicles away from the incident refers to this.
What is the Critical Wheel Angle?
This is the chassis manufacturer’s specified maximum load-carrying capacity of a vehicle having two axle systems. The in-service weight should always be equal or less than this.
What is Gross Vehicle Weight Rating (GVWR)?
Also known as "brake by wire" or "stability control."
What are electronic brake systems?
Term coined for when a vehicle outruns the sound waves produced by an electronic siren. Typically occurs around 55mph.
What is "sirencide?"
This type of railroad crossing does not have a traffic control device, and the decision to stop or proceed rests entirely in the hands of the operator.
What are passive crossings?
This is an area of danger at the space between the furthermost point of the angle (usually at the front left or right side of the vehicle) and the area where traffic passes.
What is the "Zero Buffer Zone?"
This is speed, and is controlled through acceleration, deceleration, and directional control.
What is velocity?
These work by altering valve timing under deceleration by opening the exhaust valves at top dead center of the stroke for an instant, releasing cylinder compression and eliminating expansion stroke. Also know as a "Jake brake."
What are compression or engine brakes?
These systems, also known as pre-emption devices, send a signal to the stoplight control box, giving priority to emergency vehicles. Ours are called Opti-cons.
What are Automated Traffic Control Systems?
This can occur on wet road surfaces at speeds as low as 30 mph. It occurs when water or slush accumulates on the roadway, causing the tires to lose contract with the road surface, limiting traction.
What is hydroplaning?
The distance between these is typically 40'.
What are skip lines?
A moving, or rolling wheel, is an example of this type of Traction.
What is dynamic traction?
These types of brakes consist of a butterfly valve that closes, restricting the flow of exhaust gasses and creating a back pressure on the engine, slowing the RPMs.
What are Exhaust Brakes?
This is made up of perception time, reaction time, and braking time.
What is total stopping distance?
This is the average reaction time.
What is 3/4 a second?
This manual provides detailed guidelines for establishing safe work zones at incidents on streets and highways.
What is the Manual of Uniform Traffic Control Devices (MUTCD)?
