In a collision where there is severe injury or death, you a. may refuse a sobriety test. b. may be forced to submit your blood against your will. c. will be assigned an additional 4 points on your driving record. user: at 20 mph the force of your car impacting a surface is about four times as great as 10 mph. a. true b. false user: drug or alcohol addiction is a chronic, relapsing illness. a. true b. false user: the implied consent law states that a. you must submit to

1) ANSWER: B. If you have been involved with a serious collision, you may actually be forced to submit your blood against your will. Even though you refuse a sobriety test, the police can still get a warrant from the judge that allows him/her to draw blood from you.

2) ANSWER: A. TRUE

Recall the formula for kinetic energy: 

From that formula we can see that doubling the speed (or velocity) of the car would result to a quadruple increase in the kinetic energy or the force of your car upon impacting a surface at 20mph compared to at 10mph.

3) ANSWER: A. TRUE

An addiction, whether to drugs or alcohol, is considered a chronic and relapsing illness since this addiction lasts for a long time and is difficult to let go of. Drug and alcohol addiction can also relapse (or return) after the illness has been treated since it only takes a small amount to go back into old habits.

4) For this question I have found the complete choices from another source. I will place them here:

A. you must submit to a sobriety test when asked by a law enforcement officer.
B. you have the option to plea bargain if arrested for D.U.I.
C. your license will automatically be canceled if you are convicted of D.U.I.

ANSWER: A. From the name itself, the Implied Consent Law assumes that your consent to take a sobriety test is already implied when you choose to drive a vehicle. Thus, when asked by an officer, you have to submit to the test.
