Sample Maryland CDL Test Questions - General Knowledge

Question 1

On Maryland roads, what does a yellow diamond sign displaying a black cross warn of?

This sign warns drivers to _____________.
  1. A A 1,000-foot road-repair area
  2. B An intersection where traffic may enter or cross
  3. C A change in the posted speed limit
  4. D A stop sign immediately ahead

Correct answer: B – An intersection where traffic may enter or cross

A yellow diamond sign with a black cross is an intersection warning sign. It tells drivers that another roadway crosses the road ahead and that traffic may approach from either side. Drivers should scan the intersection, control their speed, and be prepared to respond to vehicles or other road users entering or crossing their path.

Question 2

A road has a posted limit of 55 mph. Using the CDL manual’s wet-road example, about how fast should you travel?

  1. A 45 mph
  2. B 55 mph
  3. C 35 mph
  4. D 30 mph

Correct answer: C – 35 mph

Wet roads can double stopping distance and make steering or braking without skidding more difficult. The CDL manual advises reducing speed by about one-third on a wet road, using a reduction from 55 mph to approximately 35 mph as its example. Actual speed must always be low enough for the driver to maintain traction and stop safely under existing conditions.

Question 3

In Maryland, what does an orange diamond sign reading “ROAD WORK AHEAD” warn drivers about?

This sign warns drivers to _____________.
  1. A A location where every vehicle must stop for a flagger
  2. B A point where drivers must turn around
  3. C Construction or maintenance activity ahead
  4. D A required detour ahead

Correct answer: C – Construction or maintenance activity ahead

A ROAD WORK AHEAD sign warns that construction or maintenance activity is approaching. Drivers should watch for workers, equipment, temporary traffic controls, lane shifts, and changing road conditions. A separate detour sign is used when traffic must follow another route, and a flagger’s directions must be followed when a flagger is present.

Question 4

A Maryland yellow diamond sign shows a smooth S-shaped arrow bending left and then right. What does it warn of?

This sign warns drivers to _________________.
  1. A A pair of sharp angular turns
  2. B Successive roadway curves in opposite directions
  3. C The beginning of an unpaved road
  4. D A single left curve

Correct answer: B – Successive roadway curves in opposite directions

The S-shaped warning symbol indicates that the roadway curves in one direction and then the other. It alerts drivers to reduce speed as needed and prepare for successive changes in direction. It does not describe the road surface, and it is different from a sign showing only one curve or angular arrows representing sharp turns.

Question 5

Which answer names the two broad categories a commercial driver should monitor ahead?

  1. A Traffic movement and road conditions
  2. B Vehicles and traffic signals only
  3. C Disabled vehicles and debris only
  4. D Curves and pavement defects only

Correct answer: A – Traffic movement and road conditions

Maryland’s CDL manual emphasizes scanning well ahead for developing traffic situations, including entering or turning vehicles and brake lights. Drivers must also recognize road conditions that may require changes in speed or position. Seeing both types of conditions early provides more time to respond safely.

Question 6

Which description correctly defines gross combination weight (GCW)?

  1. A The combined weight of cargo, the driver, and passengers
  2. B The manufacturer's maximum weight rating for one vehicle
  3. C The actual weight of the trailer and its cargo only
  4. D The actual total weight of the power unit, trailer or trailers, and cargo

Correct answer: D – The actual total weight of the power unit, trailer or trailers, and cargo

Gross combination weight is the actual total weight of the complete combination. It includes the power unit, each towed unit, and the cargo being carried. Counting only the trailer and cargo leaves out the power unit and does not give the combination’s total weight.
