During the day, it is compulsory to switch on the appropriate lighting...
A)only when conditions exist that reduce visibility.
B)when travelling in HOV (VAO) lanes.
C)when travelling through underpasses or road sections affected by the tunnel sign.Correct
All vehicles travelling between sunset and sunrise, or at any time of day in tunnels, underpasses and road sections affected by the "Tunnel" sign, or at any time of day when meteorological or environmental conditions significantly reduce visibility, must have the appropriate lighting switched on.
Answer a) is not correct because daytime lights must be used not only when conditions reduce visibility, but also in tunnels or underpasses, in reversible lanes, in circumstantial additional lanes and in lanes running in the opposite direction to the usual one.
In HOV (VAO) lanes it is not compulsory to have lights on, except when required due to visibility conditions.
