Final answer:
The statement is true; there are 3 feet of open space on each side of a vehicle that is 6 feet wide within a lane that is 12 feet wide.
Step-by-step explanation:
If a lane is twelve feet wide and a vehicle is six feet wide, the amount of open space on each side of the vehicle can be calculated by subtracting the width of the vehicle from the width of the lane, and then dividing the result by two. Therefore, the open space on each side of the vehicle would be:
(12 feet - 6 feet) / 2 = 6 feet / 2 = 3 feet of open space on each side of the vehicle.
This confirms that the statement "in position 1, there is three feet of open space on each side of the vehicle" is True (A).
