A cement producing company operates its own fleet of cement mixers ranging from mini-mixers based on a 7.5 tonne chassis to larger vehicles based on 4 axle 32 tonne chassis. All the larger vehicles are fitted with double drive axles and diff locks.
The smaller vehicles are generally used for small deliveries to private builders or householders. The larger vehicles generally service larger building developments and sites.

• Seek fresh air immediately and do nothing until the ambulance arrives: No, seeking fresh air is correct but it is also important to take other action as soon as possible e.g. flushing mouth, skin and eyes with cool water for at least 15 minutes.
• Seek fresh air immediately, if the dust is on your skin or eyes rinse it off with cool water for at least 15 minutes: Yes, the fresh air may blow some of the dust away and will certainly help breathing. It is important to wash away any dust form skin or eyes with cool or room-temperature water for at least 15 minutes.

• Just one of those things that local residents will have to put up with for the time being: No, the local residents should not have to put up with a practice that may have potentially dangerous consequences.
• Because the spray suppression equipment on the trucks is not working efficiently: No, concrete mixers are exempt from the requirements to fit spray suppression equipment so it probably is not fitted to these trucks.
• Illegal and both drivers and operator could have legal action, including imprisonment, taken against them: Yes, leaving anything likely to cause a danger on the highway is illegal and both driver and operator could have enforcement action, including prosecution, taken against them.

Correct Answer: C
Explanation: • Ensure that their tachograph mode switch is set to "other work": No, if they are driving away from the site on a public road then the tachograph must be set to "drive". In most modern tachographs the unit will automatically select the "drive" mode for the 1st man position anyway.
• Do nothing: No, drivers have several responsibilities when re-joining a public highway.
• Clean any mud from their boots: No, although this may be good practice it is not a requirement.
• Ensure that the vehicle does not deposit mud, concrete or other material from its wheels, body or chutes, onto the public highway: Correct - and the best answer here.

Correct Answer: B
Explanation: • 8 hours: No, this is not true.
• 10 hours: No, the drivers will have a maximum 10 hour driving period but that does not prevent then from doing other non-driving work.
• 16 hours: No, it is less than this because of the requirement for all HGV drivers working under EU drivers hours law to have a daily rest of at least 9 hours in every 24 hour period.
• 15 hours: Yes, there is no maximum duty period but the shortest daily rest that a driver may take in any 24 hour period is 9 hours and. if we take that 9 hours away from 24 we are left with a maximum duty period of 15 hours.

Correct Answer: A
Explanation: • Because they will keep their feet drier than safety boots: No, although probably true, this is not the reason for the change of footwear and certainly not the best answer here
• It will save wear on their safety boots: No, this may well be so but it is not the best answer here
• Wet concrete will damage leather safety boots: No, this may be the case but it is not the reason for this change of footwear
• Because concrete, particularly when wet. can cause third degree burns if it contacts the skin: Correct, cement, when mixed with water produces highly alkaline calcium hydroxide
