Vehicles used for transporting sand are large and heavily loaded. They usually have a big blind spot and require a brake distance much longer than that of a heavy vehicle. Therefore, when travelling behind such vehicles:

AYou should increase the following distance so as to avoid collisions and accidents caused by objects fallen off themOfficial answer
BYou should reduce the following distance so as to prevent the vehicle behind from crashing into yours
CYou can reduce the following distance because there is enough time to brake
DYou should travel at high speed so that you can overtake them when you need to escape from objects fallen off them
2 of 9 · Fascicule 5, question 69

Although there is no need to worry too much about being hit by unknown objects, drivers who are travelling in front of a vehicle transporting sand and gravel should pay attention to their surroundings and, especially:

AThey should not brake suddenly, otherwise the vehicle behind could crash into themOfficial answer
BThey should travel at low speed and stay close to the vehicle transporting sand and gravel, so as to avoid the danger caused by it trying to overtake them
CThey should travel at high speed and in no way allow the vehicle behind to overtake them
DThey can brake suddenly so as to warn the vehicle behind to keep a distance
3 of 9 · Fascicule 5, question 70

Large vehicles often block the view of small vehicle drivers travelling behind and make them unable to discern the road condition ahead. Therefore, it is necessary to keep a bigger distance when travelling behind large vehicles, so that there will be more time to react when the unexpected happens. For this purpose, the normal safe distance should be increased by:

A10%
B20%
C30%
D50%Official answer
4 of 9 · Fascicule 5, question 71

When driving behind large vehicles, you should keep a bigger following distance in order to be safe, and:

AYou should change lane so that you do not share the same one with the large vehicles, as well as avoid travelling alongside themOfficial answer
BYou should not, under all circumstances, overtake them
CYou should not change lane
DYou should not overtake them, but you can travel alongside them
5 of 9 · Fascicule 5, question 72

There are large vehicles that do not respect the traffic rules. They tailgate the small vehicles and flash their headlights to threaten them. Such illegal behaviours, of course, need to be eliminated. Meanwhile, if you happen to travel in front of one of these large vehicles, you need to find ways to protect yourself. Which of the following is the most recommended?

AChange lane or move to the side of the road so as to allow the large vehicle to pass
BAdjust slightly the angle of the rearview mirror and do not look at it for a few moments so that your normal vision will not be affected by the strong lights
CWrite down the licence plate number of the large vehicle that does not respect the traffic rules, for the purpose of denouncing it or for future actions
DAll of the aboveOfficial answer
6 of 9 · Fascicule 5, question 81

The back of a large vehicle is a blind spot for its own driver, and there is a part of this area that its driver cannot see even with the help of the rearview mirror for checking the sides. Therefore, when a large vehicle goes in reverse, there should be someone to help to give instructions to its driver. However, if there is no one to help, the driver who is travelling behind the large vehicle:

AShould honk the horn as a warning and, if possible, move back to give more space to the reversing large vehicle or change lane to avoid any riskOfficial answer
BShould not honk the horn so as not to disturb the reverse manoeuvre of the large vehicle in front
CShould immediately abandon the vehicle to avoid collision
DShould immediately move back to give more space to the reversing large vehicle
7 of 9 · Fascicule 5, question 82

Some drivers of large vehicles like to travel at high speed and change lanes frequently for overtaking. In this case:

AThose travelling in front of a large vehicle should move slightly to the left side to make it easier for the large vehicle to change lane or overtake and, in order to show their intention to give way for overtaking, use the left indicatorOfficial answer
BThose travelling in front of a large vehicle should move slightly to the right side to make it easier for the large vehicle to change lane or overtake and, in order to show their intention to give way for overtaking, use the right indicator
CThose travelling in front of a large vehicle should keep driving at high speed so as to prevent being overtaken by it
DThose travelling in front of a large vehicle should brake abruptly to allow it to overtake
8 of 9 · Fascicule 5, question 83

Some drivers of large vehicles like to travel at high speed and change lanes frequently for overtaking. In this case:

AThose travelling behind on the right side of a large vehicle should, upon knowing its intention to change to the right lane, slow down when conditions allow so as to give way to itOfficial answer
BThose travelling behind on the right side of a large vehicle should speed up and drive away before it can change to their lane
CThose travelling behind on the right side of a large vehicle should immediately honk the horn and speed up, so as to prevent it from changing lane
DThose travelling behind on the right side of a large vehicle should, in all situations, brake abruptly to allow it to change lane
9 of 9 · Fascicule 5, question 84

Some drivers of large vehicles like to travel at high speed and change lanes frequently for overtaking. In this case:

AThose travelling behind on the left side of a large vehicle should be careful as it may try to overtake on the left. Therefore, they should maintain a safe distance and give way to itOfficial answer
BThose travelling behind on the left side of a large vehicle can continue to drive at high speed, because large vehicles do not overtake on the left
CThose travelling behind on the left side of a large vehicle should, in all situations, brake abruptly to allow it to overtake on the left
DThose travelling behind on the left side of a large vehicle should immediately honk the horn and speed up, so as to prevent it from changing lane
