Joseph is driving a double decker trailer, he had to take a diversion over an exposed section of the motorway in high winds. He has a load to put on the trailer which will only fill half of the trailer.
Joseph is stopped by DVSA to check his driver's hours. It was discovered that he took a 30 minute break followed by a 15 minute break. It also showed that Joseph had finished last night at 21:00 and started this morning at 05:00. When Joseph has finished he has to un-couple the trailer.

Correct Answer: B B
Explanation: • A: No, greater stability is always achieved if the weight is carried as low as possible.
• C: No, this pattern would place all the weight over the drive axle of the tractor unit increasing the likelihood of an axle overweight. It also places no weight over the semi-trailer axled thereby reducing any braking effect on those three axles.
• D: No, this pattern does not put any weight over the drive axles over the tractor unit and could lead to vehicle instability.
• B: Yes, this follows the principle of placing most weight as low as possible to achieve greatest stability.

A 15 minutes then 30 minutes
B 18 minutes then 27 minutes
C 20 minutes then 25 minutes
D 30 minutes then 30 minutes
Correct Answer: A 15 minutes then 30 minutes
Explanation: • 20 minutes then 25 minutes: No, to comply with Article EU 561/2006, the first break must be of at least 15 minutes and the second break must be of at least 30 minutes.
• 18 minutes then 27 minutes: No, to comply with Article EU 561/2006, the first break must be of at least 15 minutes and the second break must be of at least 30 minutes.
• 30 minutes then 30 minutes: No, this pattern does meet the definition under Article 7 of EU 561/2006 but it is not the best answer here as it "wastes" 15 minutes of a driver's working period.
• 15 minutes then 30 minutes: Yes, this complies with Article 7 of EU 561/2006.
A 1 hour
B 2 hours
C 3 hours
D 4 hours
Correct Answer: A 1 hour
Explanation: • 2 hours: No, finishing at 21.00 and re-starting at 05.00 hrs gives an 8 hour rest period. This is one hour short of a 'reduced daily rest' period and 3 hours short of a normal 'daily rest' period.
• 3 hours: No, this does meet the requirement of a daily rest period of 11 hours, however, the question asks 'How many hours is Joseph short of a 'reduced daily' period.
• 4 hours: No, this is too long.
• 1 hour: Yes, this meets the requirement of a 'reduced daily rest' and is the most efficient use of a driver's working time in this example.
A 10 hours
B 11 hours
C 12 hours
D 9 hours
Correct Answer: B 11 hours
Explanation: • 9 hours: No, this is s reduced daily rest under Article 8(2) of Article 561/2006.
• 10 hours: No, this is s reduced daily rest under Article 8(2) of Article 561/2006.
• 12 hours: No, Article 8(2) defines a 'daily rest' as a period of 11 hours and a 'reduced daily rest period' as a period '...of at least 9 hours but less than 11 hours'.
• 11 hours: Yes.
Correct Answer: B A buffer lane
Explanation: •A buffer lane is used to give a greater lateral gap between high-sided vehicles and other traffic in windy conditions. This allows vehicles that are more affected by the cross-winds to move without endangering other road users.
A Have no effect on the vehicle
B Only affect the trailer and not the tractor unit
C Prolong the journey as he would have to slow down to control the vehicle
D They would make it harder to keep the vehicle in the lane
Correct Answer: D They would make it harder to keep the vehicle in the lane
Explanation: • Prolong the journey as he would have to slow down to control the vehicle: No, although a possible correct answer, this is not the 'best answer' in this selection.
• Have no effect on the vehicle: No, clearly any significant wind would have some effect.
• Only affect the trailer and not the tractor unit: No, anything that affects the trailer must also have some effect on the tractor unit since the two are connected.
• They would make it harder to keep the vehicle in the lane: Yes, as they would be exerting a force on the side of the vehicle.
