Can I ride my bicycle on the shoulder of a road that has a "do not drive on shoulder" sign in Texas?
Below is an example of this configuration.
By far, the shoulder seems like the safest option to use here.
However, according to the traffic laws in Texas it seems that bicycle travel on a shoulder with this sign is prohibited for bicycles as well:
The DO NOT DRIVE ON SHOULDER (R4-3a) sign (see Figure 2B-8) may be used on roadways with usable shoulders where an engineering study determines that an area of the shoulder should not be used by moving vehicles.
So, is it really prohibited to ride a bicycle on a shoulder if a "do not drive on shoulder" sign is present?
