How Many Questions in HGV Theory Test

How Many Questions in HGV Theory Test

Becoming an HGV driver in the UK requires passing several tests to ensure that drivers are well-prepared and knowledgeable about road safety and vehicle operation. The HGV theory test is one of the critical steps in this process. Many aspiring drivers have questions about the format and content of these tests, and understanding what to expect can help alleviate some of the anxiety associated with them.


How Many Questions in HGV Theory Test


The HGV theory test consists of two main parts: multiple choice questions and hazard perception. In the multiple choice section, you will be required to answer 100 questions, and you must score at least 85 to pass. The hazard perception test involves watching 19 video clips and identifying developing hazards, with a minimum passing score of 67 out of 100.

The specific requirements for the theory test can vary depending on the category of the vehicle. For example, category C (rigid lorries) and category C+E (articulated lorries) may have different focuses in their questions, reflecting the different skills needed for these vehicles.


What to Expect on an HGV Driving Assessment



Importance in Evaluating Practical Skills and Road Safety


The HGV driving assessment is crucial for evaluating a driver's practical skills and ensuring they can operate their vehicle safely and efficiently. This assessment helps identify any gaps in a driver’s practical knowledge and ensures they are road-ready.


Format of the Assessment


The driving assessment typically includes a practical driving test, which assesses a driver's ability to handle the vehicle in various conditions and scenarios. This may involve urban driving, motorway driving, and handling specific maneuvers such as reversing and parking.


Examples of Assessment Questions


Typical assessment questions focus on the practical aspects of driving an HGV, such as vehicle checks, handling in different traffic conditions, and responses to emergency situations.


How to Best Prepare for Both Theory Tests and Assessments



Resources and Study Materials


Preparation is key to passing both the theory and practical tests. There are many resources available, including official DVSA guides, practice tests, and study apps. These materials cover everything from the Highway Code to specific HGV driving techniques and hazard perception.


Examples of Typical Questions and Answers
