One reason you should drive slowly around farm vehicles is:

One reason is that Most farm vehicles are relatively noisier than other Vehicles. hence the driver might not hear you coming

Explanation:

Farm vehicles are vehicles used mainly to work on mechanized farms, this machines make farm processes very easy and convenient unlike the traditional market procedures which were much more stressful and difficult to use.

Farm vehicles include tractors, plowing machines and tillers. these machines are driven around farm settlements and they are very slow compared to regular vehicles and they are relatively noisy hence the driver might not hear you coming or honking behind him hence it is advisable to drive around Farm vehicles at a slow speed to avoid collisions.

you can lose ranking 2 ways.

1) you don't have enough points due to you expending them by asking questions/your answers are deleted.

2) your brainliest's expired. this means that brainliests, once they exceed the 30 day limit, expires. this is to ensure that you continue to contribute into the community at a constant rank if you want to continue to have/exceed the rank you have right now.

if you go to profile, and click "show more information" located on the bottom left of the box with your information (on top of the questions answered, questions asked, and friends), you will be given the following information (example):

member since : 02/13/2017, 18: 11

questions answered: 9741

questions asked: 162

no. of brainliest answers: 1575

brainliest answers in last 30 days: 10

warnings: 0 view

questions/answers reported: 2637

questions/answers incorrectly reported: 64

look at the "brainliest answers in the last 30 days". this is the one that will affect your rank other than your points. again, once your brainliest expires (was earned 31+ days ago), it will not be counted.
