Bridge clearance = 20tan14° = 4.99 m
Required clearance = 4.3+0.5 = 4.8m
The truck can safely pass under the bridge.

From David: Yes because 20*tan(14) = 4.986 and 4.3+0.5 = 4.8

To safely pass under the bridge must be 4.8 meters below the bridge. This is the sum of the height of the bridge and the clearance. The height and the horizontal distance are the two sides of a right triangle. The ratio of these two numbers is equal to the tangent of the angle.
h ÷ 20 = tan 14
h = 20 * tan 14
This is approximately 5 meters. Since this is greater than the total clearance, the truck will pass safely under the bridge. I hope this is helpful for you.

From RealPro: Yes 20tan14° > 4.8
