This week's tip, offered in the New York DMV Driver's Manual, concerns sudden headlight failure. "Fade to black" may work in a screenplay, but it can be a pretty scary development on the highway. So you may want to pass this advice along to your fleet drivers as a friendly reminder.
If your headlights suddenly go out, try your vehicle's four-way flashers, parking lights and directional signals. These may still work and should give you enough light to get safely off the road. If your headlights begin to dim, drive to a nearby service station, or pull off the road and go for help.
