You may legally park your vehicle a. within 15 ft of a fire hydrant b. within 50 ft of the nearest rail of a railroad crossing c. in front of a public driveway d. within 18 inches of the curb

D. Within 18 inches of the curb

  D. Within 18 inches of the curb.

Explanation:

  In what respects to fire hydrants, you must park at least 15 ft away from it, a full standard sedan car length, in order to let the firefighters work in good conditions.

  In a railroad crossing, you must be at least 30 ft away from it.

  It is forbidden to park in front of a public driveway if you do it any way you risk to have your car lifted away.

  Now the correct answer is option D. You must park within 18 inches of the curb with both tires parallel to it. If you park more distance from it you risk getting your car scratched.

  I hope this answer helps you.
