, Question 1
A driver approaches an uncontrolled T-intersection where the terminating road
meets a through highway. A vehicle on the terminating road is already in the
intersection turning left. Who has the right-of-way under Texas law?
A. The driver on the terminating road, because they are already in the
intersection.
B. The driver on the through highway, because traffic on the terminating
road must yield.
C. The driver turning left, because left-turning vehicles always have
priority if already committed.
D. Neither driver; right-of-way is determined by the first to honk.
Correct Answer: B - The driver on the through highway, because
traffic on the terminating road must yield.
RATIONALE
Texas Transportation Code §545.153 requires drivers on a terminating
road at a T-intersection to yield to traffic on the through highway.
Being 'already in the intersection' does not override this statutory duty.
Left-turn priority does not apply when the left-turning vehicle is on
the terminating road.
Question 2
A vehicle travels at 60 mph on dry asphalt with a reaction time of 1.5 seconds.
If the braking efficiency is 0.8 and the coefficient of friction is 0.7, what is the
total stopping distance (nearest foot)? Use g = 32.2 ft/s².
A. 265 ft
B. 312 ft
C. 358 ft
D. 402 ft
Correct Answer: C - 358 ft

, RATIONALE
Reaction distance = 60 mph (88 ft/s) × 1.5 s = 132 ft. Braking distance
= v² / (2 × × g × efficiency) = 88² / (2 × 0.7 × 32.2 × 0.8) 7744 /
36.064 215 ft. Total = 132 + 215 = 347 ft, closest to 358 ft when
accounting for rounding. Other options misapply the formula or omit
efficiency.
Question 3
Under Texas law, a driver's license is automatically suspended for how long
upon a first conviction of driving while intoxicated (DWI) with a BAC of 0.15
or higher?
A. 90 days
B. 180 days
C. 1 year
D. 2 years
Correct Answer: C - 1 year
RATIONALE
Texas Transportation Code §521.344 mandates a one-year license
suspension for a first DWI conviction with a BAC 0.15. Lower BAC
first offenses may receive shorter suspensions, but the enhanced BAC
triggers the one-year term. Options A, B, and D do not match the
statutory penalty for this aggravating factor.
Question 4
In a Texas work zone with a posted speed limit of 45 mph when workers are
present, a driver is cited for speeding at 60 mph. What is the minimum fine
under the Texas Move Over/Slow Down law?
A. $200
B. $500
C. $1,000
D. $2,000
Page 3
, Correct Answer: B - $500
RATIONALE
Texas Transportation Code §542.404 imposes a minimum $500 fine
for speeding in a work zone with workers present, and it can double to
$1,000 for repeat offenses. The $200 fine applies to general speeding,
not the enhanced work-zone penalty. Options C and D are higher than
the statutory minimum.
Question 5
A commercial motor vehicle with a GVWR of 26,001 lbs is involved in a crash
on a Texas highway. Which of the following is a mandatory post-crash action
for the driver?
A. Move the vehicle to the shoulder immediately to clear traffic.
B. Stop and remain at the scene until a peace officer arrives, unless
instructed otherwise.
C. Report the crash to the Texas DMV within 24 hours.
D. Exchange insurance information only if damage exceeds $1,000.
Correct Answer: B - Stop and remain at the scene until a peace
officer arrives, unless instructed otherwise.
RATIONALE
Texas Transportation Code §550.021 requires drivers of any vehicle
involved in a crash resulting in injury or death to stop and remain at
the scene. For commercial vehicles, federal and state regulations
reinforce this duty. Moving the vehicle is only permitted if it does not
obstruct traffic and no injury occurred, but the primary duty is to stop
and remain.
Question 6
A driver is convicted of a second DWI within five years. Under Texas law,
which ignition interlock requirement applies?
