Sample Norway Theory Test - Category CE Practice Questions

Try these sample questions to review concepts for the Norway Theory Test - Category CE exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1When inspecting an automatic drawbar coupling (tilhengerkopling, e.g., VBG or Ringfeder) after hitching a full trailer, what does the position of the visual indicator pin (kontrolltapp) verify?
A.That the drawbar coupling bolt is fully down and locked in its secure travel position
B.That the trailer pneumatic service line has reached working pressure
C.That the coupling eye is lubricated with adequate chassis grease
D.That the trailer turntable is locked against steering rotation
Explanation: The mechanical indicator pin on an automatic drawbar coupling shows the physical position of the coupling bolt. When the pin is fully in its locked position, it confirms that the coupling mechanism has closed completely and the safety latch has engaged around the drawbar eye.
2What immediate mechanical verification must the driver perform after coupling a tractor to a semitrailer before connecting lines and winding up the landing legs fully?
A.Perform a gentle pull test (rykktest) in low gear against the trailer brakes to confirm kingpin lock engagement
B.Raise the tractor air suspension to maximum height to pop the fifth wheel jaws open
C.Disconnect the red air supply hose to check if the safety pin snaps shut
D.Release the trailer parking brake and let the combination roll backwards downhill
Explanation: A gentle pull test (rykktest) in low gear against the locked trailer brakes confirms mechanically that the fifth wheel locking jaws have fully closed around the kingpin. Performing this test while the landing legs are still close to the ground prevents the semitrailer from dropping onto the tractor drive tyres if the coupling failed to lock.
3When coupling standard twin pneumatic lines (red supply and yellow control) to a trailer, in what sequence should the glad-hand couplings be connected?
A.Connect the yellow control line first, followed by the red supply line
B.Connect the red supply line first, followed by the yellow control line
C.Connect both lines simultaneously using a high-pressure clamp
D.The connection sequence is completely irrelevant for pneumatic safety
Explanation: When coupling air lines, connect the yellow control (signal) line first, and then the red supply (feed) line. Connecting the yellow line first ensures that service braking signals are intact before the red line pressurizes the system and releases the trailer spring parking brakes.
4When uncoupling pneumatic lines from a trailer, what is the correct disconnection sequence for the red and yellow air lines?
A.Disconnect the red supply line first, then disconnect the yellow control line
B.Disconnect the yellow control line first, then disconnect the red supply line
C.Bleed both lines through the reservoir drain cock before touching any coupling
D.Disconnect the electrical EBS cable first to vent all air lines automatically
Explanation: When uncoupling, disconnect the red supply line first. This instantly vents the supply port on the trailer relay emergency valve, automatically triggering emergency braking and applying the trailer spring brakes so the trailer cannot roll away.
5What is the primary operational advantage of the Duo-Matic compressed air coupling system compared to conventional twin red and yellow glad-hands?
A.It combines supply and control lines into a single ergonomic connector that prevents cross-connection and allows rapid operation
B.It eliminates the need for air reservoirs and moisture separators on the trailer
C.It allows hydraulic and pneumatic fluid to mix into a single pressurized circuit
D.It doubles the maximum operating pressure of the trailer brake actuators to 25 bar
Explanation: The Duo-Matic coupling integrates both the supply and control channels into one dual-orifice quick-coupling head. This prevents cross-connecting lines, enables rapid one-handed coupling, and protects sealing surfaces from dirt when closed.
6What is the critical safety function of the standard ISO 7638 7-pin electrical connection between a towing vehicle and trailer?
A.It supplies dedicated electrical power and digital CAN-bus data for the trailer Electronic Braking System (EBS/ABS)
B.It charges the auxiliary high-voltage propulsion batteries on the trailer chassis
C.It operates only the tail lamps, brake lamps, and license plate lighting
D.It sends hydraulic fluid pulses to synchronize steering axles on full trailers
Explanation: The ISO 7638 connector is the mandatory heavy-vehicle EBS/ABS interface. It supplies steady electrical current to the trailer EBS control unit and pressure modulators, and provides CAN-bus communication to synchronize braking response and anti-lock functions between truck and trailer.
7While driving a lorry and trailer, the yellow trailer ABS/EBS warning indicator on the instrument panel remains illuminated. What does this indicate?
A.A malfunction has occurred in the trailer ABS/EBS system; conventional pneumatic service brakes still operate, but without anti-lock protection
B.The trailer air reservoirs are empty and the vehicle will halt immediately
C.The trailer coupling pin has completely unlocked from the drawbar
D.The trailer tyres have lost all inflation pressure
Explanation: A continuous yellow trailer ABS/EBS warning indicates an active electronic fault in the trailer's braking control system (such as a faulty wheel speed sensor or disconnected ISO 7638 cable). The foundation pneumatic service brakes continue to function, but wheel anti-lock regulation and electronic load-sensing calculations may be disabled.
8How should a driver decide whether wear on a drawbar coupling bolt (koplingsbolt) and drawbar eye (trekkøye) is acceptable?
A.Measure with the specified gauge and compare the result with the coupling manufacturer's wear limit
B.Wear up to 10.0 mm is permissible as long as the locking handle latches
C.No measurable wear whatsoever is permitted; components must be replaced annually regardless of dimensions
D.Wear is acceptable until the coupling bolt rattles audibly at idle
Explanation: Coupling designs have manufacturer-specific inspection points and rejection limits. The driver uses the correct wear gauge or measurement procedure and removes the combination from service when the specified limit is exceeded; one generic millimetre value is not safe for every coupling.
9What is the correct way to assess wear on a semitrailer kingpin?
A.Use the specified kingpin gauge at the required measuring points and apply the manufacturer's rejection limit
B.Nominal diameter 3 inches (76.2 mm), with a maximum wear limit down to 70.0 mm
C.Nominal diameter 1 inch (25.4 mm), with a maximum wear limit down to 24.0 mm
D.Nominal diameter 4 inches (101.6 mm), with no allowable wear
Explanation: A standard semitrailer commonly uses a two-inch kingpin, but the precise measuring points and allowable wear come from the component specification. A proper gauge and the manufacturer's limit are more reliable than applying one remembered diameter to every installation.
10What is the function of the turntable (dreiekrans / styrekrans) on a full trailer (slepvogn), and what maintenance does it require?
A.It allows the front dolly axle to pivot smoothly relative to the trailer chassis and requires regular greasing and periodic inspection for axial/radial play
B.It acts as a hydraulic shock absorber and requires daily transmission fluid changes
C.It locks the front wheels rigidly to prevent any turning during forward driving
D.It generates compressed air for the trailer braking system through wheel rotation
Explanation: The turntable (dreiekrans) forms the pivotal steering bearing between the trailer chassis and the front dolly axle on a full trailer. It carries heavy vertical and steering forces, requiring regular lubrication via grease nipples to prevent binding, as well as checking for excessive axial and radial play.
