potholed road
snowy road
wet road
percentage
20 40 60 80 100
wet road
dry road
snowy road
potholed road

Explanation:

Step1: Identify the relevant category

The red segments in the bar graph represent "Following all the rules". We need to compare the length of these red segments for each road condition.

Step2: Compare the red segments

- For Dry road: The red segment ends around 40 - 50? Wait, no, looking at the x - axis (percentage from 0 - 100). Let's check each bar:
- Dry road: The red (Following all rules) segment: Let's see the bar. The first (dry road) bar: the red part, from the start (after the dark blue "Eating/drinking") to the purple "Not using indicators". Let's estimate the length.
- Potholed road: The red segment length.
- Snowy road: The red segment here: looking at the snowy road bar, the red (Following all rules) segment seems to be the longest. Wait, no, let's re - examine. Wait, the x - axis is percentage (0 - 100). Let's list the road conditions and the approximate end of the red segment:
- Dry road: Red segment ends around, say, 40? No, wait the bar for dry road: the red part, from the left (after dark blue) to the purple (Not using indicators) is, maybe up to 40 - 50?
- Potholed road: Red segment ends around, maybe 40?
- Snowy road: The red segment in the snowy road bar: looking at the graph, the snowy road bar's red (Following all rules) segment is longer. Wait, no, wait the labels: the red is "Following all the rules". Let's check the length of the red part for each road condition:
- Dry road: Red part length (percentage) – let's see the bar. The dry road bar: the red part, from the start (after dark blue) to the purple (Not using indicators) – maybe around 40 - 50?
- Potholed road: Red part – similar to dry?
- Snowy road: The red part here: looking at the bar, the red segment (Following all rules) is longer. Wait, no, wait the snowy road bar: the red part goes up to around 60? Wait, no, the x - axis is 0 - 100. Let's look at the four bars:
- Dry road: Red (Following all rules) segment: Let's count the units. The first bar (dry road): the red part, from the left (dark blue "Eating/drinking" is a small segment) then red (Following all rules) to the purple (Not using indicators). Let's see the length.
- Potholed road: Red segment: similar to dry?
- Snowy road: The red segment here: the bar for snowy road, the red (Following all rules) segment is longer. Wait, no, wait the correct one: looking at the graph, the snowy road's red (Following all rules) segment is the longest among dry, potholed, snowy, and wet. Wait, no, wait the wet road: the red segment is shorter. Wait, maybe I made a mistake. Wait, let's look again. The question is "Which road condition had the highest percentage of drivers following all rules?". The red color is "Following all rules". So we need to find which bar has the longest red segment.
Looking at the four bars:
- Dry road: Red segment length (percentage) – let's say around 40 - 50?
- Potholed road: Red segment – around 40?
- Snowy road: Red segment – looking at the bar, the red part (Following all rules) is longer. Wait, no, wait the snowy road bar: the red segment is from the left (after dark blue) to the purple (Not using indicators) and it seems to be the longest. Wait, but wait the answer options include "snowy road". Wait, let's check again. Wait, maybe I misread. Wait the four options are wet road, dry road, snowy road, potholed road.
Wait, let's look at the graph again. The snowy road bar: the red (Following all rules) segment is the longest. So the road condition with the highest percentage of drivers following all rules is snowy road.

Answer:

snowy road
