Is it permissible for me to work as a bus driver in France, given the presence of advertisements for alcohol or women's lingerie on the buses, which change weekly, knowing that I have no control over the type of these advertisements?

If it is highly probable or certain that there are forbidden advertisements (such as for alcohol or revealing clothing) on the bus, then it is not permissible to work as a driver for it, because it constitutes aiding in sin. However, if the advertisements are mostly permissible, then it is permissible to work, unless the existence of forbidden advertisements becomes known.
