After the publication of the original article [1] it was highlighted that there was an omission regarding the online resources for the traffic signs in the section of “Experimental stimuli”. The single online source listed in the Fig. 2 should be removed and the exact detailed two online sources for the traffic signs should be cited in the section “Experimental stimuli”. This correction article shows the correct and incorrect version of this section and the caption of Fig. 2. The authors apologize for the inconvenience.

Incorrect

Experimental stimuli

Ten symbolic traffic signs (Fig. 2) were used as stimuli in this study. Among those signs, five widely used road signs (S1—do not turn right; S4—do not turn left; S7—U-turn is prohibited; S9—do not go straight; S10—turn right) were hypothesized to be easy to comprehend, and the other five new road signs in UK (S2—no vehicle carrying explosives; S3—headphone users may be lost in music; S5—tourist area; S6—caution texter; S8—risk of grounding) were hypothesized to be hard to comprehend.
