which allows vehicles to pass through the end terminal. Extending the guardrail to move the end terminal upstream of the fixed object (see Figure 5) is a good solution. Often, a clear area for the end terminal can be found a short distance upstream of the initial location. Figure 5:Extending guardrail to move end terminal upstream of fixed object.
