1In Nigeria, what shape is primarily used for regulatory road signs that prohibit certain actions?

A.Triangular

B.Circular

C.Rectangular

D.Octagonal

Explanation: According to the Nigerian Highway Code, regulatory signs are circular. Prohibitory regulatory signs are circular with a red border (e.g., speed limits, no entry, no overtaking). Triangular signs are warning signs, rectangular signs are informative, and stop signs are octagonal.

2What is the primary meaning of a circular road sign with a blue background and white arrows or figures in Nigeria?

A.It indicates a hazard ahead (Warning sign)

B.It provides general information (Informative sign)

C.It gives positive instruction or mandatory action (Mandatory sign)

D.It indicates a temporary detour due to construction

Explanation: Circular signs with a blue background are mandatory regulatory signs. They give positive instructions that drivers must follow, such as 'Keep Right', 'One Way', or indicating minimum speed limits. Prohibitory regulatory signs, by contrast, have red borders.

3In the Nigerian Highway Code, what does a triangular road sign with a red border and the apex pointing upwards represent?

A.A prohibitory instruction

B.A warning or hazard ahead

C.A mandatory speed limit

D.An informational direction

Explanation: Triangular signs with a red border and the apex pointing upwards are warning signs. They alert drivers to hazards or changes in road conditions ahead, such as narrow bridges, sharp bends, or pedestrian crossings, allowing them to adjust speed accordingly.

4Which of the following road signs is octagonal (eight-sided) in Nigeria?

A.Yield sign

B.No Overtaking sign

C.Stop sign

D.Speed Limit sign

Explanation: The 'Stop' sign is the only octagonal (eight-sided) road sign in Nigeria. This unique shape allows drivers to recognize it from both the front and the back, even if the sign is covered by dirt or snow.

5A circular sign with a red border containing the number '80' means:

A.The recommended speed is 80 km/h under good conditions

B.The maximum legal speed limit is 80 km/h

C.The minimum required speed is 80 km/h

D.The distance to the next town is 80 kilometers

Explanation: A circular sign with a red border indicates a prohibition or maximum limit. A number inside such a circle defines the maximum speed limit in kilometers per hour (km/h) that vehicles must not exceed.

6What is the meaning of a warning sign displaying two arrows pointing in opposite vertical directions?

A.No overtaking allowed in both directions

B.Two-way traffic ahead on a single carriageway

C.Dual carriageway ends ahead

D.The road splits into two separate routes

Explanation: A warning sign showing two vertical arrows pointing in opposite directions indicates that two-way traffic is ahead. This typically warns drivers transitioning from a one-way street or dual carriageway onto a single carriageway with opposing traffic flow.

7What does a rectangular sign with a blue background and a white letter 'H' indicate in Nigeria?

A.Heavy vehicle parking zone

B.Hospital ahead

C.Highway patrol station

D.Hazardous cargo route

Explanation: In Nigeria, a rectangular sign with a blue background is an informative sign. A white 'H' symbol indicates a hospital ahead, alerting drivers to drive quietly and be alert for pedestrians or ambulance movements.

8What does a warning sign showing a narrow bridge ahead indicate to a commercial vehicle driver?

A.The driver must speed up to cross the bridge quickly

B.The bridge is wider than the road approach

C.The width of the bridge is narrower than the road, and heavy vehicles should prepare to yield

D.Overtaking is permitted on the bridge

Explanation: The 'Narrow Bridge' warning sign indicates that the upcoming bridge has a narrower carriageway than the approaching road. Heavy and commercial vehicles, due to their width, must approach with caution and be prepared to yield to oncoming traffic.

9What does a circular sign showing a red border and a silhouette of a bicycle indicate?

A.A designated route for bicycles only

B.Watch out for cyclists ahead

C.No entry for bicycles

D.Bicycle parking zone

Explanation: A circular sign with a red border is prohibitory. Therefore, a bicycle silhouette inside a red-bordered circle indicates that bicycles are prohibited from entering or using that particular road or highway.

10What does a single solid white line painted down the center of a two-way road mean?

A.Overtaking is permitted at any time

B.Overtaking is prohibited from both directions

C.It indicates the edge of the road boundary

D.Parking is permitted along the center line

Explanation: According to the Nigerian Highway Code, a solid (continuous) line in the center of the road means overtaking or crossing the line is prohibited from both directions. Drivers must stay within their lane.

Frequently Asked Questions

What is the passing score for the FRSC commercial driver's licence test?

The passing score for the FRSC commercial driver's licence CBT theory test is 60%. The test consists of multiple-choice questions on road safety, vehicle checks, traffic regulations, and speed limits in Nigeria.

What are the driver's licence classes for commercial drivers in Nigeria?

The primary classes are Class C (commercial vehicles under 3 tonnes, like taxis), Class E (commercial/heavy vehicles other than articulated vehicles, like buses and rigid body trucks), and Class G (articulated vehicles, like trailers and fuel tankers).

What is the speed limit for trucks and tankers on Nigerian expressways?

Under FRSC regulations, 20-tonne trucks are limited to 80 km/h, while 40-tonne articulated vehicles (tankers and trailers) are limited to 60 km/h on expressways. These limits are programmed into the mandatory Speed Limiting Device (SLD).

Is a Speed Limiting Device (SLD) mandatory for commercial vehicles in Nigeria?

Yes, the FRSC mandates that all commercial vehicles, including buses, taxis, trucks, and tankers, must have an officially approved and calibrated Speed Limiting Device installed by an accredited vendor. Drivers can verify their device registration by texting 'confirmsld [PlateNumber]' to 33811.

How does the FRSC demerit point system work?

The FRSC tracks driver infractions using demerit points: accumulating 10-14 points results in a warning letter; 15-20 points leads to temporary licence suspension; and 21 or more points results in the complete withdrawal of the driver's licence.

What is the legal blood alcohol concentration (BAC) limit in Nigeria?

The legal limit for BAC in Nigeria is 0.05% (or 0.5 g/L). Driving under the influence of alcohol (DUI) carries 5 penalty points and a ₦5,000 fine under FRSC regulations.
