Convex Mirrors
{Warning
A convex mirror can make things,
like other vehicles, look farther
away than they really are. If you cut
too sharply into the right lane, you
could hit a vehicle on the right.
Check the inside mirror or glance
over your shoulder before changing
lanes.
The driver and passenger side mirrors
are convex shaped. A convex mirror's
surface is curved so more can be seen
from the driver seat.
